Law enforcement agency in the context of "Maritime patrol"

The Police (Polish: Policja, [pɔˈlit͡sja] ) is the national civilian police service of Poland. It is the country’s primary law enforcement agency, responsible for public security and order as well as the prevention and investigation of crime. It operates under the authority of the Ministry of the Interior and Administration.

Polish Police is headed by the Commander-in-Chief of Police, subordinate to the Minister of the Interior and Administration. The Police is supported by municipal forces of city guards, having less legal authority and with jurisdiction only over prosecuting contraventions.

A law enforcement agency (LEA) has powers, which other government subjects do not, to enable the LEA to undertake its responsibilities. These powers are generally in one of six forms:

• Exemptions from laws
• Intrusive powers, for search, seizure, and interception
• Legal deception
• Use of force and constraint of liberty
• Jurisdictional override
• Direction

The types of powers and law exemptions available to a LEA vary from country to country.

A political demonstration is an action by a mass group or collection of groups of people in favor of a political or other cause or people partaking in a protest against a cause of concern; it often consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, in order to hear speakers. It is different from mass meeting.

Demonstrations may include actions such as blockades and sit-ins. They can be either nonviolent or violent, with participants often referring to violent demonstrations as "militant." Depending on the circumstances, a demonstration may begin as nonviolent and escalate to violence. Law enforcement, such as riot police, may become involved in these situations. Police involvement at protests is ideally to protect the participants and their right to assemble. However, officers don't always fulfill this responsibility and it's well-documented that many cases of protest intervention result in power abuse. It may be to prevent clashes between rival groups, or to prevent a demonstration from spreading and turning into a riot.

A police station is a facility operated by police or a similar law enforcement agency that serves to accommodate police officers and other law enforcement personnel. The role served by a police station varies by agency, type, and jurisdiction, but in larger agencies there may be multiple police stations that serve as regional or area sub-headquarters for personnel assigned to certain beats, administrative divisions, or police units, while in smaller agencies there may be fewer stations or even one singular police headquarters.

The San Francisco Police Department (SFPD) is the municipal law enforcement agency of the City and County of San Francisco, as well as San Francisco International Airport in San Mateo County. In 2000, the SFPD was the 11th largest police department in the United States.

The SFPD (along with the San Francisco Fire Department and the San Francisco Sheriff's Department) serves an estimated population of 1.2 million, including the daytime-commuter population and thousands of other tourists and visitors.

The federal government of the United States empowers a wide range of federal law enforcement agencies (informally known as the "Feds") to maintain law and public order related to matters affecting the country as a whole.

While the majority of federal law enforcement employees work for the Department of Justice and Homeland Security, there are dozens of other federal law enforcement agencies under the other executive departments, as well as under the legislative and judicial branches of the federal government.

The National Crime Agency (NCA) is a national law enforcement agency in the United Kingdom. It is the UK's lead agency against organised crime; human, weapon and drug trafficking; cybercrime; and economic crime that goes across regional and international borders, but it can be tasked to investigate any crime. The NCA has a strategic role as part of which it looks at serious crime in aggregate across the UK, especially analysing how organised criminals are operating and how they can be disrupted. To do this, it works closely with regional organised crime units (ROCUs), local police forces, and other government departments and agencies. It is not a police force as such, but many of its employees do have the power of a constable.

It is the UK's point of contact for foreign agencies such as Interpol, Europol and other international law enforcement agencies. On a day-to-day basis, the NCA assists police forces and other law enforcement agencies (and vice versa) under voluntary assistance arrangements. In extremis, the NCA Director General has the power to direct a chief officer of a police force to give directed assistance with NCA tasks where necessary (but only with consent of the relevant Secretary of State). The NCA itself can also be directed by the Secretary of State to give directed assistance to a police force or other law enforcement agency.

Crisis negotiation is a law enforcement technique used to communicate with people who are threatening violence (workplace violence, domestic violence, suicide, or terrorism), including barricaded subjects, stalkers, criminals attempting to escape or evade arrest, and hostage-takers. Crisis negotiation is often initiated by the first officer(s) on the scene.
