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.
Exclusionary ruleIn the United States, the exclusionary rule is a legal rule, based on constitutional law, that prevents evidence collected or analyzed in violation of the defendant's constitutional rights from being used in a court of law. This may be considered an example of a prophylactic rule formulated by the judiciary in order to protect a constitutional right.
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.
Civil disorderCivil disorder, also known as civil disturbance, civil unrest, or social unrest, is a situation arising from a mass act of civil disobedience (such as a demonstration, riot, strike, or unlawful assembly) in which law enforcement has difficulty maintaining their authority. Any number of things may cause civil disorder, whether it is a single cause or a combination of causes; however, most are born from political grievances, economic disparities, social discord, but historically have been the result of long-standing oppression by a group of people towards another.
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.
Deadly forceDeadly force, also known as lethal force, is the use of force that is likely to cause serious bodily injury or death to another person. In most jurisdictions, the use of deadly force is justified only under conditions of extreme necessity as a last resort, when all lesser means have failed or cannot reasonably be employed. Firearms, bladed weapons, explosives, and vehicles are among those weapons the use of which is considered deadly force.
