PoliceThe police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health, and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility.
Law enforcement agencyA law enforcement agency (LEA) is any government agency responsible for the enforcement of the law. 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' 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.
Criminal justiceCriminal justice is the delivery of justice to those who have been accused of committing crimes. The criminal justice system is a series of government agencies and institutions. Goals include the rehabilitation of offenders, preventing other crimes, and moral support for victims. The primary institutions of the criminal justice system are the police, prosecution and defense lawyers, the courts and the prisons system.
Use of forceThe use of force, in the context of law enforcement, may be defined as the "amount of effort required by police to compel compliance by an unwilling subject". Use of force doctrines can be employed by law enforcement officers and military personnel on guard duty. The aim of such doctrines is to balance the needs of security with ethical concerns for the rights and well-being of intruders or suspects. Injuries to civilians tend to focus attention on self-defense as a justification and, in the event of death, the notion of justifiable homicide.
Law enforcement officerA law enforcement officer (LEO), or peace officer in North American English, is a public-sector or private-sector employee whose duties primarily involve the enforcement of laws, protecting life & property, keeping the peace, and other public safety related duties. Law enforcement officers are designated certain powers & authority by law to allow them to carry out their responsibilities. Modern legal codes use the term peace officer (or in some jurisdictions, law enforcement officer) to include every person vested by the legislating state with law enforcement authority.
Search and seizureSearch and seizure is a procedure used in many civil law and common law legal systems by which police or other authorities and their agents, who, suspecting that a crime has been committed, commence a search of a person's property and confiscate any relevant evidence found in connection to the crime. Some countries have certain provisions in their constitutions that provide the public with the right to be free from "unreasonable searches and seizures". This right is generally based on the premise that everyone is entitled to a reasonable right to privacy.
United States Bill of RightsThe United States Bill of Rights comprises the first ten amendments to the United States Constitution. Proposed following the often bitter 1787–88 debate over the ratification of the Constitution and written to address the objections raised by Anti-Federalists, the Bill of Rights amendments add to the Constitution specific guarantees of personal freedoms and rights, clear limitations on the government's power in judicial and other proceedings, and explicit declarations that all powers not specifically granted to the federal government by the Constitution are reserved to the states or the people.
Emergency serviceEmergency services and rescue services are organizations that ensure public safety, security, and health by addressing and resolving different emergencies. Some of these agencies exist solely for addressing certain types of emergencies, while others deal with ad hoc emergencies as part of their normal responsibilities. Many of these agencies engage in community awareness and prevention programs to help the public avoid, detect, and report emergencies effectively.
EmergencyAn emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency.
Miranda warningIn the United States, the Miranda warning is a type of notification customarily given by police to criminal suspects in police custody (or in a custodial interrogation) advising them of their right to silence and, in effect, protection from self-incrimination; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. Named for the U.S. Supreme Court's 1966 decision Miranda v. Arizona, these rights are often referred to as Miranda rights.
Crime preventionCrime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice. Criminologists, commissions, and research bodies such as the World Health Organization, United Nations, the United States National Research Council, the UK Audit Commission have analyzed their and others' research on what lowers rates of interpersonal crime.
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.
Police carA police car (also called a police cruiser, police interceptor, patrol car, area car, cop car, prowl car, squad car, radio car, or radio motor patrol) is a ground vehicle used by police and law enforcement for transportation during patrols and responses to calls for service. A type of emergency vehicle, police cars are used by police officers to patrol a beat, quickly reach incident scenes, and transport and temporarily detain suspects, all while establishing a police presence and providing visible crime deterrence.
Public securityPublic security or public safety is the prevention of and protection from events that could endanger the safety and security of the public from significant danger, injury, or property damage. It is often conducted by a state government to ensure the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being, survival, and prosperity.
RiotA riot or mob violence is a form of civil disorder commonly characterized by a group lashing out in a violent public disturbance against authority, property, or people. Riots typically involve destruction of property, public or private. The property targeted varies depending on the riot and the inclinations of those involved. Targets can include shops, cars, restaurants, state-owned institutions, and religious buildings. Riots often occur in reaction to a grievance or out of dissent.
Emergency telephone numberAn emergency telephone number is a number that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services; these often differ only by the last digit. In many countries, dialing either 1-1-2 (used in Europe and parts of Asia) or 9-1-1 (used in the Americas) will connect callers to emergency services.
