Based on what is known, the officers used the appropriate level of force considering their reasonable perception of the threat level initiated by the subject, Miriam Carey, 34. Carey’s use of the Infiniti, and the fact that she rammed government property and federal officers, posed a potentially lethal threat to the officers. She also posed a lethal threat to the public in the immediate area, including her child.
While it was obvious Carey used her vehicle in a hazardous manner to gain unauthorized entry to government property, there was no way to discern whether the vehicle contained any explosive material or other weapons that could have fatally wounded the officers or bystanders. Officers assess available threat indicators in micro-seconds and react accordingly.
Critics often ask why officers didn't shoot at the tires. The answer is that law enforcement tactics don't follow Hollywood fiction. They must work in the real world. Warning shots and shots at tires are usually prohibited by agency policy because they pose a greater threat to those in the immediate area. Shooting at tires would create a dangerous ricochet swarm that exposes anyone in the immediate area to significant risk.
The officers should be commended for their performance. The second-guessing, "could have" committee will draw upon the subject's publicized mental health history, and somehow suggest the officers should have known this and tempered their response. That's nonsense. There's no pause button for an officer to hit while being confronted by a lethal threat. Law enforcement officers receive training on how to deal with subjects with known mental illness, but in this situation, the officers needed to objectively assess what was known at the time of the attacks and respond appropriately.
While the loss of this young woman’s life is regrettable, it's fortuitous that no law enforcement officers or innocent civilians were killed. The Secret Service and Capitol Police have a very dangerous job, and they carry out their respective high-risk missions with the utmost degree of professionalism. I applaud them for their unwavering service to our country, and for confronting volatile subjects to keep us safe.
