Q: Recently, a woman in Washington led police on a car chase near the Capitol. It was reported that she was unarmed. Why was it necessary for police to shoot and kill her as opposed to shooting out her tires?

A: Law enforcement authorities have had few comments about the shooting death of Miriam Carey that ended a car chase near the U.S. Capitol on Oct. 3. Carey, who was driving a 2010 Nissan Infiniti, refused to stop at a checkpoint near the White House and knocked over an officer before driving toward the Capitol. She struck a U.S. Secret Service vehicle before Secret Service agents and U.S. Capitol Police fired at the vehicle, according to information from a search warrant posted by The Washington Post. Carey began driving in reverse when officers fired more shots into the car, killing her near a Capitol guard booth. At least 17 shots were fired at the car, the paper reported. Officers in the District of Columbia are prohibited from shooting "at or from a moving vehicle unless deadly force is being used against the officer or another person," according to guidelines enacted in 1998. They also state: "a moving vehicle is not considered deadly force." Terrance Gainer, the U.S. Senate's sergeant at arms who also has served as the chief of the Capitol Police, told the Post: "… But the thing that's distinctive about this is it was not your typical traffic violation. … We operate in an environment under the constant threat of attack from suicide bombers and improvised explosive devices."
