Revolver
–
A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. Revolvers might be regarded as a subset of pistols, or as a subset of handguns. Though the term revolver usually only refers to handguns, other firearms may also have a revolving chamber and these include some models of grenade launchers, shotguns, and rifles. Most revolvers contain five or six rounds in the cylinder, though the original name was revolving gun, the short-hand revolver is universally used. The revolver allows the user to fire multiple rounds without reloading, each time the user cocks the hammer, the cylinder revolves to align the next chamber and round with the hammer and barrel, which gives this type of firearm its name. In a single-action revolver, the user pulls the back with his free hand or thumb. In a double-action revolver, pulling the trigger moves the back, then releases it. Loading and unloading a double-action revolver requires the operator to swing out the cylinder and insert the proper ammunition, the first guns with multichambered cylinders that revolved to feed one barrel were made in the late 16th century in Europe. They were expensive and rare curiosities, not until the 19th century would revolvers become common weapons of industrial production. One of the first was a flintlock revolver patented by Elisha Collier in 1814, the first percussion revolver was made by Lenormand of Paris in 1820 and the first percussion cap revolver was invented by the Italian Francesco Antonio Broccu in 1833. He received a prize of 300 francs for his invention, although he did not patent it, however, in 1835 a similar handgun was patented by Samuel Colt, who would go on to make the first mass-produced revolver. The first cartridge revolvers were produced around 1854 by Eugene Lefaucheux, revolvers soon became standard for nearly all uses. In the early 20th century, semi-automatic pistols were developed, which can hold more rounds, Automatic pistols also have a flat profile, more suitable for concealed carry. Automatic pistols have almost completely replaced revolvers in military and law enforcement use, revolvers still remain popular as back-up and off-duty handguns among American law enforcement officers and security guards. Also, revolvers are still common in the American private sector as defensive, in the development of firearms, an important limiting factor was the time it took to reload the weapon after it was fired. While the user was reloading, the weapon was useless, several approaches to the problem of increasing the rate of fire were developed, the earliest being multi-barrelled weapons which allowed two or more shots without reloading. Later weapons featured multiple barrels revolving along a single axis, the earliest examples of what today is called a revolver were made in Germany in the late 16th century. These weapons featured a barrel with a revolving cylinder holding the powder

Stainless steel
–
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a steel alloy with a minimum of 10. 5% chromium content by mass. Stainless steel is notable for its resistance, and it is widely used for food handling. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, however, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure, Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steel differs from carbon steel by the amount of chromium present, unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by making it easier for more iron oxide to form, since iron oxide has lower density than steel, the film expands and tends to flake and fall away. In comparison, stainless steels contain sufficient chromium to undergo passivation and this layer prevents further corrosion by blocking oxygen diffusion to the steel surface and stops corrosion from spreading into the bulk of the metal. Passivation occurs only if the proportion of chromium is high enough, Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. Storage tanks and tankers used to transport orange juice and other food are made of stainless steel. This also influences its use in kitchens and food processing plants, as it can be steam-cleaned and sterilized. High oxidation resistance in air at ambient temperature is achieved with addition of a minimum of 13% chromium. The chromium forms a layer of chromium oxide when exposed to oxygen. The layer is too thin to be visible, and the metal remains lustrous, the layer is impervious to water and air, protecting the metal beneath, and this layer quickly reforms when the surface is scratched. This phenomenon is called passivation and is seen in other metals, corrosion resistance can be adversely affected if the component is used in a non-oxygenated environment, a typical example being underwater keel bolts buried in timber. When stainless steel parts such as nuts and bolts are forced together, when forcibly disassembled, the welded material may be torn and pitted, a destructive effect known as galling. Galling can be avoided by the use of materials for the parts forced together, for example bronze and stainless steel. However, two different alloys electrically connected in a humid, even mildly acidic environment may act as a voltaic pile, nitronic alloys, made by selective alloying with manganese and nitrogen, may have a reduced tendency to gall. Additionally, threaded joints may be lubricated to provide a film between the two parts and prevent galling, low-temperature carburizing is another option that virtually eliminates galling and allows the use of similar materials without the risk of corrosion and the need for lubrication

.357 Magnum
–
The.357 S&W Magnum, or simply.357 Magnum, is a revolver cartridge with a. 357-inch bullet diameter. It was created by Elmer Keith, Phillip B, Wesson of firearms manufacturers Smith & Wesson and Winchester. It is based upon Smith & Wessons earlier.38 Special cartridge, the.357 Magnum cartridge was introduced in 1934, and its use has since become widespread. This cartridge started the Magnum era of handgun ammunition, the.357 Magnum cartridge is notable for its stopping power. The.357 Magnum was collaboratively developed over a period in the early to mid-1930s by a group of individuals in a response to Colts.38 Super Automatic. Tests at the revealed that those vests defeated any handgun cartridge traveling at less than about 1,000 feet per second. Colts.38 Super Automatic just edged over that velocity and was able to penetrate car doors and vests that bootleggers and gangsters were employing as cover. Though.38 and.357 would seem to be different diameter chamberings, they are in fact identical, the.38 Special nomenclature relates to the previous use of heeled bullets, which were the same diameter as the case. Thus, the only difference in the two cartridges is a slight difference in length, solely for safety purposes. Much credit for the. 357s early development is given to hunter and experimenter Elmer Keith, the. 38-44 HV load used the. 38-Special cartridge loaded to a much higher velocity than standard. 38-Special ammunition. The. 38-44 revolvers were made by using a.44 Special size gun with the barrel bored to accept. 357-caliber bullets, since the frame, cylinder, and barrel were much stronger than the standard.38 Special components, it was capable of withstanding much higher pressures. The. 38-44 HV round, while no longer available, was in most cases the equal of the later.357 Magnum, which works at more than double the pressure of standard.38 Special. Elmer Keith also contributed the Keith-style bullet, which increased the mass of bullet located outside the cartridge, the Keith bullet also employed a large, flat meplat, thus enabling rapid energy transfer for greater wounding properties. At the same time, this design does not deform like a hollow point. These characteristics of the Keith bullet make it suitable for hunting applications as well as for target shooting. In order to reassert itself as the leading law-enforcement armament provider, Smith & Wesson developed the.357 Magnum, Wesson leading the effort within Smith & Wesson, along with considerable technical assistance from Phillip B. Sharpe, a member of the Technical Division staff of the National Rifle Association, the new round was developed from Smith & Wessons existing.38 Special round. It used a different powder load, and ultimately the case was extended by 1⁄8 inch, the case extension was more a matter of safety than of necessity

Action (firearms)
–
In firearms terminology, an action is the mechanism that handles the ammunition or the method by which that mechanism works. Breech-loading weapons have actions, actions are not present on muzzleloaders. The mechanism that fires a muzzle-loader is called the lock, actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also short, long, and magnum if it is in reference to the length of the rifle’s receiver. The short action rifle usually can accommodate a cartridge length of 2.8 in or smaller, the long action rifle can accommodate a cartridge of 3.34 in, and the magnum action rifle can accommodate cartridges of 3.6 in, or longer in length. Manual operation is a term describing any type of firearm action that is loaded one shot at a time by the user rather than automatically. For example, break action is a form of operation using a simple hinge mechanism that is manually unlatched by the operator. These are actions wherein the breechblock lowers or drops into the receiver to open the breech, there are two principal types of dropping block, the tilting block and the falling block. In a tilting or pivoting block action, the breechblock is hinged on a pin mounted at the rear, when the lever is operated, the block tilts down and forward, exposing the chamber. The best-known pivoting block designs are the Peabody, the Peabody–Martini, the original Peabody rifles, manufactured by the Providence Tool Company, used a manually cocked side-hammer. The 1871 Martini–Henry which replaced the trapdoor Snider–Enfield was the standard British Army rifle of the later Victorian era, charles H. Ballards self-cocking tilting-block action was produced by the Marlin Firearms Company from 1875, and earned a superlative reputation among long-range Creedmoor target shooters. Surviving Marlin Ballards are today highly prized by collectors, especially those mounted in the elaborate Swiss-style Schützen stocks of the day. A falling-block action is a firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon. Examples of firearms using the falling block action are the Sharps rifle, in a rolling block action the breechblock takes the form of a part-cylinder, with a pivot pin through its axis. The operator rotates or rolls the block to open and close the breech, it is a simple, rugged, a break action is a type of firearm where the barrel are hinged and can be broken open to expose the breech. The earliest metallic-cartridge breechloaders designed for military issue began as conversions of muzzle-loading rifle-muskets. The upper rear portion of the barrel was filed or milled away, an internal angled firing pin allowed the re-use of the rifles existing side-hammer. The Allin action made by Springfield Arsenal in the US hinged forward, france countered in 1866 with its superior Chassepot rifle, also a paper-cartridge bolt action

Police
–
A police force is a constituted body of persons empowered by the state to enforce the law, protect property, and limit civil disorder. Their powers include the use of force. Law enforcement, however, constitutes part of policing activity. Policing has included an array of activities in different situations, in some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Many police forces suffer from police corruption to a greater or lesser degree, the police force is usually a public sector service, meaning they are paid through taxes. Alternative names for police force include constabulary, gendarmerie, police department, police service, crime prevention, protective services, law enforcement agency, members may be referred to as police officers, troopers, sheriffs, constables, rangers, peace officers or civic/civil guards. As police are often interacting with individuals, slang terms are numerous, many slang terms for police officers are decades or centuries old with lost etymology. One of the oldest, cop, has largely lost its slang connotations and this is derived from πόλις, city. Law enforcement in ancient China was carried out by prefects for thousands of years since it developed in both the Chu and Jin kingdoms of the Spring and Autumn period, in Jin, dozens of prefects were spread across the state, each having limited authority and employment period. Under each prefect were subprefects who helped collectively with law enforcement in the area, some prefects were responsible for handling investigations, much like modern police detectives. The concept of the system spread to other cultures such as Korea. In ancient Greece, publicly owned slaves were used by magistrates as police, in Athens, a group of 300 Scythian slaves was used to guard public meetings to keep order and for crowd control, and also assisted with dealing with criminals, handling prisoners, and making arrests. Other duties associated with modern policing, such as investigating crimes, were left to the citizens themselves, in the Roman empire, the army, rather than a dedicated police organization, provided security. Local watchmen were hired by cities to some extra security. Magistrates such as fiscal and quaestors investigated crimes. There was no concept of public prosecution, so victims of crime or their families had to organize and their duties included apprehending thieves and robbers and capturing runaway slaves. The vigiles were supported by the Urban Cohorts who acted as a heavy-duty anti-riot force, in medieval Spain, Santa Hermandades, or holy brotherhoods, peacekeeping associations of armed individuals, were a characteristic of municipal life, especially in Castile. These organizations were intended to be temporary, but became a fixture of Spain

.38 Special
–
The.38 Smith & Wesson Special is a rimmed, centerfire cartridge designed by Smith & Wesson. It is most commonly used in revolvers, although some semi-automatic pistols, in other parts of the world, it is known by its metric designation of 9×29. 5mmR or 9. 1×29mmR. Noted for its accuracy and manageable recoil, the.38 Special remains the most popular cartridge in the world more than a century after its introduction. It is used for shooting, formal target competition, personal defense. Despite its name, the caliber of the.38 Special cartridge is actually. 357–.358 inches, except for case length, the.38 Special is identical to the.38 Short Colt.38 Long Colt, and.357 Magnum. This allows the.38 Special round to be fired in revolvers chambered for the.357 Magnum. Upon its introduction, the.38 Special was originally loaded with black powder and this.38 Special variant incorporated a 200 grains round-nosed lead Lubaloy bullet, the.38 Super Police. Remington-Peters also introduced a similar loading, testing revealed that the longer, heavier 200 grains. 357-calibre bullet fired at low velocity tended to keyhole or tumble upon impact, providing more shock effect against unprotected personnel. This cartridge was called the.38 S&W Super Police or the. 38/200, britain would later adopt the. 38/200 as its standard military handgun cartridge. In 1930, Smith & Wesson introduced a large frame.38 Special revolver with a 5-inch barrel and fixed sights intended for police use, the following year, a new high-power loading called the. That same year, Colt Firearms announced that their Colt Official Police would also handle high-speed.38 Special loadings, the. 38/44 high-speed cartridge came in three bullet weights,158 grains,150 and 110 grains, with either coated lead or steel jacket, metal-piercing bullets. The media attention gathered by the. 38/44 and its ammunition eventually led Smith & Wesson to develop a new cartridge with a longer case length in 1934—this was the.357 Magnum. During World War II, some U. S. aircrew were issued.38 Special S&W Victory revolvers as sidearms in the event of a forced landing, the new military.38 Special loading propelled its 158 grains bullet at a standard 850 ft/s from a 4-inch revolver barrel. During the war, many U. S. naval and marine aircrew were also issued red-tipped.38 Special tracer rounds using either a 120 or 158 gr bullet for emergency signaling purposes. In 1956, the U. S. Air Force adopted the Cartridge, Caliber.38, Ball M41, a military variant of the.38 Special cartridge designed to conform to the rules of land warfare. By 1961, a slightly revised M41.38 cartridge specification known as the Cartridge, Caliber.38 Ball, Special, a variant of the standard M41 cartridge with a semi-pointed, unjacketed lead bullet was later adopted for CONUS police and security personnel. At the same time.38 tracer cartridges were reintroduced by the US Navy, Marines, tracer cartridges in.38 Special caliber of different colors were issued, generally as part of a standard aircrew survival vest kit. A request for more powerful.38 Special ammunition for use by Air Police and security personnel resulted in the Caliber.38 Special, Ball, in 1972, the Federal Bureau of Investigation introduced a new.38 +P loading that became known as the FBI Load

Winchester Repeating Arms Company
–
The Winchester Repeating Arms Company was a prominent American maker of repeating firearms, located in New Haven, Connecticut. The ancestor of the Winchester Repeating Arms Company was the Horace Smith and Daniel Wesson partnership of Norwich, Jennings rifle was a commercial failure, and Robbins & Lawrence ceased production in 1852. Smith designed a much-improved rifle based on Jennings, and the partners also hired away Robbins & Lawrence shop foreman Benjamin Tyler Henry. In 1855 the Smith & Wesson partnership, in order to manufacture what they called the Volcanic lever-action rifle and pistol, sought investors and its largest stockholder was clothing manufacturer Oliver Winchester. The Volcanic rifle had only limited success, the company moved to New Haven in 1856, but by the end of that year became insolvent. Oliver Winchester and his partner John M. Davies purchased the firms assets from the remaining stockholders. After Smiths departure Benjamin Henry continued to work with a Smith development project, the self-contained metallic rimfire cartridge, Henry also supervised a new rifle design based loosely on the Volcanic to use the new ammunition, retaining only the general form of the breech mechanism and the tubular magazine. This became the Henry rifle of 1860, which was manufactured by the New Haven Arms Company, the Henry rifle ensured New Haven Arms success, and together with the Spencer rifle established the lever-action repeater in the firearms market. In 1866 Benjamin Henry, angered over what he believed was inadequate compensation, Oliver Winchester, hastening back from Europe, forestalled the move and reorganized New Haven Arms yet again as the Winchester Repeating Arms Company. Another extremely popular model was rolled out in 1873, the Model 1873 introduced the first Winchester center fire cartridge, the. 44-40 WCF. These rifle families are known as the Gun That Won the West. The Model 1873 was followed by the Model 1876, a version of the 73. It was chambered for longer, more powerful cartridges such as. 45-60 WCF. 45-75 WCF, Oliver Winchester died in December 1880, his son and successor, William Wirt Winchester, died of tuberculosis four months later. William Wirt Winchesters widow, Sarah Winchester, used her inheritance, several of these are still in production today through companies such as Browning, Rossi, Navy Arms and others which have revived several of the discontinued models or produced reproductions. The early years of the century found the Winchester Repeating Arms Company competing with new John Browning designs. The race to produce the first commercial self-loading rifle brought forth the.22 rimfire Winchester Model 1903 and later centerfire Model 1905, Model 1907, and Model 1910 rifles. Winchester engineers, after ten years of work, designed the Model 1911 to circumvent Brownings self-loading shotgun patents, one of Winchesters premier engineers, T. C. Johnson, was instrumental in the development of these self-loading firearms and went on to superintend the designs of Winchesters classic Model 1912, Model 52 and Model 54

United States Border Patrol
–
The United States Border Patrol is an American federal law enforcement agency. Its mission is to detect and prevent illegal aliens, terrorists and terrorist weapons from entering the United States and it is the mobile, uniformed law enforcement arm of U. S. Customs and Border Protection, a component of the U. S. Department of Homeland Security. With over 21,000 agents, the U. S, Border Patrol is one of the largest law enforcement agencies in the United States. The inspectors, usually called mounted guards, operated out of El Paso, though they never totaled more than 75, they patrolled as far west as California trying to restrict the flow of illegal Chinese immigration. In March 1915, Congress authorized a group of mounted guards. Most rode on horseback, but a few operated automobiles, motorcycles, although these inspectors had broader arrest authority, they still largely pursued Chinese aliens trying to avoid the National Origins Act and Chinese Exclusion Act of 1882. These patrolmen were Immigration Inspectors, assigned to stations. U. S. Army soldiers along the southwest border performed intermittent border patrolling, aliens encountered illegally in the U. S. by the Army were directed to the immigration inspection stations. Texas Rangers were also assigned to patrol duties by the state. Border Patrol was founded on May 28,1924 as an agency of the United States Department of Labor to prevent illegal entries along the Mexico–United States border, the first Border Patrol station began operations in Detroit, Michigan in June 1924. A second station in El Paso, Texas began operations in July 1924, additional operations were established along the Gulf Coast in 1927 to perform crewman control to ensure that foreign crewmen departed on the same ship on which they arrived. In 1932, the Border Patrol was divided into two offices, Mexican border operations were directed from El Paso, Texas and Canadian border operations were directed from Detroit, Michigan. The Canadian border operations from Detroit employed more men than the El Paso operations along the Mexican border because of a focus on the prevention of smuggling during prohibition. Franklin Delano Roosevelts Executive Order 6166 formed the Immigration and Naturalization Service in 1933 by consolidation of the Bureau of Immigration and the Bureau of Naturalization. Following the outbreak of World War II in Europe, Border Patrol staffing doubled to 1,500 in 1940, and the INS was moved from the Department of Labor to the U. S. Department of Justice. INS was decommissioned in March 2003 when its operations were divided between CBP, United States Citizenship and Immigration Services, and U. S. Immigration, the Border Patrol also erected 33 permanent interior checkpoints near the southern border of the United States. Agents are assigned primarily to the Mexico–United States border, where they control drug trafficking, the Border Patrols priorities have changed over the years. In 1986, the Immigration Reform and Control Act placed renewed emphasis on controlling illegal immigration by going after the employers that hire illegal aliens, the belief was that jobs were the magnet that attracted most illegal aliens to come to the United States

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

United States Department of Homeland Security
–
Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management. It was created in response to the September 11 attacks, in fiscal year 2017, it was allocated a net discretionary budget of $40.6 billion. With more than 240,000 employees, DHS is the third largest Cabinet department, after the Departments of Defense, Homeland security policy is coordinated at the White House by the Homeland Security Council. Other agencies with significant homeland security responsibilities include the Departments of Health and Human Services, Justice and its stated goal is to prepare for, prevent, and respond to domestic emergencies, particularly terrorism. On March 1,2003, DHS absorbed the Immigration and Naturalization Service, in doing so, it divided the enforcement and services functions into two separate and new agencies, Immigration and Customs Enforcement and Citizenship and Immigration Services. The investigative divisions and intelligence gathering units of the INS and Customs Service were merged forming Homeland Security Investigations, additionally, the border enforcement functions of the INS, including the U. S. Border Patrol, the U. S. Customs Service, the Federal Protective Service falls under the National Protection and Programs Directorate. The Department of Homeland Security is headed by the Secretary of Homeland Security with the assistance of the Deputy Secretary, the Department contains the components listed below. Agencies, United States Citizenship and Immigration Services, Processes and examines citizenship, residency, U. S. Immigration and Customs Enforcement, Law enforcement agency divided into two bureaus, An agency that enforces U. S. It also investigates crimes against the U. S. monetary system including the crime of counterfeiting U. S. currency, Federal Emergency Management Agency, agency that oversees the federal governments response to natural disasters like earthquakes, hurricanes, tornadoes, floods, forest fires, etc. National Protection and Programs Directorate, risk-reduction, encompassing both physical and virtual threats and their associated human elements, Federal Protective Service, Federal law enforcement and security agency that protects and investigates crimes against U. S. federal buildings, properties, assets, and federal government interests. National Cybersecurity Center In an August 5,2002 speech, President Bush said, to secure freedom in the homeland. Prior to the creation of DHS, American presidents had referred to the U. S. as the nation or the republic, also unprecedented was the use, from 2002, of the phrase the homeland by White House spokespeople. In 2011 the Department of Homeland Security phased out the old Homeland Security Advisory System with a two-level National Terrorism Advisory System, the system has two types of advisories, Alerts and Bulletins. Alerts are issued when there is specific and credible information of a terrorist threat against the United States, Alerts themselves have two levels, Elevated and Imminent. An Elevated Alert is issued when there is information about an attack. An Imminent Alert is issued when the threat is very specific, many procedures at government facilities are tied in to the alert level, for example a facility may search all entering vehicles when the alert is above a certain level. After resigning, Tom Ridge stated that he did not always agree with the threat level adjustments pushed by other government agencies
