Excessive force refers to the use of more physical power than is necessary to handle a situation, particularly by law enforcement officers. This can occur during arrests, crowd control, or other interactions where officers may apply force to subdue individuals. The concept is often evaluated in the context of the Fourth Amendment, which protects against unreasonable searches and seizures. When excessive force is used, it can lead to serious injuries or even fatalities, raising concerns about police accountability and public safety. Various organizations, including the American Civil Liberties Union (ACLU), advocate for policies and training to prevent such incidents and promote fair treatment by law enforcement.
