Counterterrorism
Counterterrorism (alternatively spelled: counter-terrorism), also known as anti-terrorism, relates to the practices, military tactics, techniques, and strategies that governments, law enforcement, businesses, and Intelligence agency, intelligence agencies use to combat or eliminate terrorism. If an act of terrorism occurs as part of a broader insurgency (and insurgency is included in the definition of terrorism) then counterterrorism may additionally employ counterinsurgency measures. The United States Armed Forces uses the term "foreign internal defense" for programs that support other countries' attempts to suppress insurgency, lawlessness, or subversion, or to reduce the conditions under which threats to national security may develop. History The first counterterrorism body to be formed was the Special Irish Branch of the Metropolitan Police, later renamed the Special Branch (Metropolitan Police), Special Branch after it expanded its scope beyond its original focus on Fenia ...

Terrorism
Terrorism, in its broadest sense, is the use of criminal violence to provoke a state of terror or fear, mostly with the intention to achieve political or religious aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants (mostly civilians and neutral military personnel). The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but became widely used internationally and gained worldwide attention in the 1970s during the Troubles in Northern Ireland, the Basque conflict, and the Israeli–Palestinian conflict. The increased use of suicide attacks from the 1980s onwards was typified by the 2001 September 11 attacks in the United States. There are various different definitions of terrorism, with no universal agreement about it. Terrorism is a charged term. It is often used with the connotation of something that is "morally wrong".

PI2G 2F
The number (; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number appears in many formulas across mathematics and physics. It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as \tfrac are commonly used to approximate it. Consequently, its decimal representation never ends, nor enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an equation involving only sums, products, powers, and integers. The transcendence of implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge. The decimal digits of appear to be randomly distributed, but no proof of this conjecture has been found. For thousands of years, mathematicians have attempted to extend their understanding of , sometimes by computing i ...

Law Enforcement Agency
A law enforcement agency (LEA) is any government agency responsible for the enforcement of the laws. Jurisdiction LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction. LEAs will have some form of geographic restriction on their ability to apply their powers. The LEA might be able to apply its powers within a country, for example the United States of America's Bureau of Alcohol, Tobacco, Firearms and Explosives or its Drug Enforcement Administration; within a division of a country, for example the Australian state Queensland Police; or across a collection of countries, for example international organizations such as Interpol, or the European Union's Europol. LEAs which operate across a collection of countries tend to assist in law enforcement activities, rather than directly enforcing laws, by facilitating the sharing of information necessary for law enforcement between LEAs within those countries, f ...

Facial Recognition System
A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image. Development began on similar systems in the 1960s, beginning as a form of computer application. Since their inception, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. Because computerized facial recognition involves the measurement of a human's physiological characteristics, facial recognition systems are categorized as biometrics. Although the accuracy of facial recognition systems as a biometric technology is lower than iris recognition and fingerprint recognition, it is widely adopted due to its contactless process. Facial recognition systems have been deployed in advanced human–comput ...

Manhunt (law Enforcement)
In law enforcement, a manhunt is an extensive and thorough search for a wanted and dangerous fugitive involving the use of police units, technology, and help from the public. A manhunt is conducted when the suspect believed to be responsible for a serious crime is at large and is believed to be within a certain area. Any police units within reach of the area will then participate in the search, each covering parts of the area. The officers will, if possible, form a perimeter around the area, guarding any and all possible escape routes from the containment. A manhunt may have one of the following outcomes: *The successful capture of the suspect within the area of the manhunt *The death of the suspect within the area of the manhunt. *Escape from the area by the suspect, followed by plans by other law enforcement agencies to search for the suspect elsewhere *The search being called off, if police determine the chances of catching the suspect are minimal Also, if the fugitive resi ...

Manhunt (military)
Manhunting is a term sometimes used for military operations by special operations forces and intelligence organizations to search for, and capture or kill important enemy combatants, known as high-value targets. It has been used particularly in the United States during the War on Terror. The most visible such operations conducted involve counterterrorist activities. Some involve government-sanctioned targeted killing or extrajudicial execution, and such operations have drawn political and legal controversy. Other military operations, such as hostage rescue or personnel recovery, employ similar tactics and techniques. The term has been used for some US operations such as Operation Red Dawn, the apprehension of Saddam Hussein, the search for Abu Musab al-Zarqawi,Chris Cuomo and Eamon McNiff"The Men in the Shadows – Hunting al-Zarqawi: Task Force 145 Is an Elite Special Ops Unit That Spent Years Tracking al-Zarqawi,"ABC News, June 9, 2006 and the killing of Osama bin Laden in M ...

Tracking System
A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing. It is important to be aware of human tracking, further details are listed below. Applications A myriad of tracking systems exists. Some are 'lag time' indicators, that is, the data is collected after an item has passed a point for example a bar code or choke point or gate. Others are 'real-time' or 'near real-time' like Global Positioning Systems (GPS) depending on how often the data is refreshed. There are bar-code systems which require items to be scanned and automatic identification (RFID auto-id). For the most part, the tracking worlds are composed of discrete hardware and software systems for different applications. That is, bar-code systems are separate from Electronic Product Code (EPC) systems, GPS systems are separate from active real time locating systems or RTLS for ex ...

Wiretapping
Telephone tapping (also wire tapping or wiretapping in American English) is the monitoring of telephone and Internet-based conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on the telephone line. Legal wiretapping by a government agency is also called lawful interception. Passive wiretapping monitors or records the traffic, while active wiretapping alters or otherwise affects it. Legal status Lawful interception is officially strictly controlled in many countries to safeguard privacy; this is the case in all liberal democracies. In theory, telephone tapping often needs to be authorized by a court, and is again in theory, normally only approved when evidence shows it is not possible to detect criminal or subversive activity in less intrusive ways. Oftentimes, the law and regulations require that the crime investigated must be at least of a certain severity. ...

Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis approaches to provide guidance and direction to assist commanders in their decisions. This aim is achieved by providing an assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and during a war itself. Most governments maintain a military intelligence capability to provide analytical and ...

Red Team
A red team or team red are a group that plays the role of an enemy or competitor to provide security feedback from that perspective. Red teams are used in many fields, especially in cybersecurity, airport security, law enforcement, the military and intelligence agencies. Overview In military wargaming, the opposing force (or OPFOR) in a simulated conflict may be referred to as a red cell; this is an interchangeable term for red team. The key theme is that the adversary (red team) leverages tactics, techniques, and equipment as appropriate to emulate the desired actor. The red team challenges operational planning by playing the role of a mindful adversary. In United States wargaming simulations, the U.S. force is always the blue team, whereas the opposing force is always the red team. When applied to intelligence work, red-teaming is sometimes called alternative analysis. Cybersecurity In cybersecurity, a penetration test involves ethical hackers trying to break into a ...

September 11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Center� ...
