Peace officers: deadly force.

Existing law authorizes a peace officer to make an arrest pursuant to a warrant or based upon probable cause, as specified. Under existing law, an arrest is made by the actual restraint of the person or by submission to the custody of the arresting officer. Existing law authorizes a peace officer to use reasonable force to effect the arrest, to prevent escape, or to overcome resistance. Existing law does not require an officer to retreat or desist from an attempt to make an arrest because of resistance or threatened resistance of the person being arrested. Under existing law, a homicide committed by a peace officer is justifiable when necessarily committed in arresting a person who has committed a felony and the person is fleeing or resisting such arrest. Existing case law deems such a homicide to be a seizure under the Fourth Amendment of the Constitution of the United States, and as such, requires the actions to be reasonable. This bill would redefine the circumstances under which a homicide by a peace officer is deemed justifiable to include when the officer reasonably believes, based on the totality of the circumstances, that deadly force is necessary to defend against an imminent threat of death or serious bodily injury to the officer or to another person, or to apprehend a fleeing person for a felony that threatened or resulted in death or serious bodily injury, if the officer reasonably believes that the person will cause death or serious bodily injury to another unless the person is immediately apprehended. The bill would also affirmatively prescribe the circumstances under which a peace officer is authorized to use deadly force to effect an arrest, to prevent escape, or to overcome resistance.
