InspectorInspector, also police inspector or inspector of police, is a police rank. The rank or position varies in seniority depending on the organization that uses it. In Australian police forces, the rank of inspector is generally the next senior rank from senior sergeant and is less senior than a superintendent (in the cases of the Queensland Police and Western Australia Police) in the other Australian police forces. Members holding the rank usually wear an epaulette featuring three silver pips, the same rank badge as a captain in the army.
Police radioPolice radio is a radio system used by police and other law enforcement agencies to communicate with one another. Police radio systems almost always use two-way radio systems to allow for communications between police officers and dispatchers. Most modern police radio systems are encrypted, and many jurisdictions have made listening to police radio frequencies as a private citizen illegal. Before police radio systems were first implemented, police officers assigned to their beat could only communicate with police command using telephone booths, call boxes, police boxes, or physical meetings.
Prefectural policeIn the law enforcement system in Japan, prefectural police are prefecture-level law enforcement agencies responsible for policing, law enforcement, and public security within their respective prefectures of Japan. Although prefectural police are, in principle, regarded as municipal police, they are mostly under the central oversight and control of the National Police Agency. As of 2017, the total strength of the prefectural police is approximately 260,400 sworn officers and 28,400 civilian staff, a total of 288,000 employees.
Provost (military police)Provosts (usually pronounced "provo" in this context) are military police (MP) whose duties are policing solely within the armed forces of a country, as opposed to gendarmerie duties in the civilian population. However, many countries use their gendarmerie for provost duties. As with all official terms, some countries have specific official terminology which differs from the exact linguistic meaning. The head of the military police is commonly referred to as the provost marshal, an ancient title originally given to an officer whose duty was to ensure that an army did no harm to the citizenry.
Bulletproof vestA bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from firearm-fired projectiles and fragmentation from explosions. The vest may come in a soft form, as worn by many police officers, prison guards, security guards, and some private citizens, used to protect against stabbing attacks or light projectiles, or hard form, using metallic or para-aramid components.
Police tactical unitA police tactical unit (PTU) is a specialized police unit trained and equipped to handle situations that are beyond the capabilities of ordinary law enforcement units because of the level of violence (or risk of violence) involved. A police tactical unit's tasks may include: executing dangerous search warrants and arrest warrants for dangerous persons; arresting or neutralizing dangerous or mentally ill armed persons; and intervening in high risk situations such as shootouts and standoffs, or hostage and terrorist incidents.
Law enforcementLaw enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. Throughout the world, law enforcement are also associated with protecting the public, life, property, and keeping the peace in society.
Metropolitan PoliceThe Metropolitan Police Service (MPS) is the territorial police force responsible for law enforcement and the prevention of crime within the ceremonial county of Greater London. In addition, it is responsible for some specialised matters throughout the United Kingdom, including national counter-terrorism measures and the protection of specific people, such as the monarch and other members of the royal family, members of the government, and other officials.
Traffic policeTraffic police (also known as traffic officers, traffic enforcement units, traffic cops, traffic monitors, or traffic enforcers) are police officers, units, and agencies who enforce traffic laws and manage traffic. Traffic police include police who patrol highways, direct traffic, and address traffic infractions. They may be a separate agency from a main police agency, a unit or division within a police agency, or a type of assignment issued to officers; they can also be part of a transportation authority or highway authority.
Watchman (law enforcement)Watchmen were organised groups of men, usually authorised by a state, government, city, or society, to deter criminal activity and provide law enforcement as well as traditionally perform the services of public safety, fire watch, crime prevention, crime detection, and recovery of stolen goods. Watchmen have existed since earliest recorded times in various guises throughout the world and were generally succeeded by the emergence of formally organised professional policing.
