Which case established that law enforcement standards are judged based on objective reasonableness?

The case that established law enforcement standards based on the principle of objective reasonableness is Graham vs. Connor. This landmark decision set a critical precedent by defining how excessive force claims are evaluated in the context of law enforcement. The court determined that the assessment of an officer's use of force should be based on the perspective of a reasonable officer on the scene at the time of the incident, rather than through hindsight. This means that the focus is on the objective circumstances surrounding the officer's decisions, taking into consideration the situation they faced, the severity of the crime, whether the suspect posed an immediate threat, and whether the suspect was actively resisting arrest.

This case is significant in shaping the legal framework within which law enforcement operates, emphasizing that the reasonableness of force is judged from an objective standpoint rather than a subjective one. This has major implications for both law enforcement and individuals involved in encounters with police, ultimately aiding in the fair evaluation of use-of-force incidents.
