Under stress few people shoot well. That has be proven. Look at the bullet vs hit ratio in war time encounters. Not the same type of incident but it is a sample none the less.The ratio is terrible. Trying to control fear, adrenaline dump agency policy, procedure, the review of your actions by your department, departmental charges, public out cry, grand jury review by the states attorney,with a possible indictment, a trail,and attorney fees, they are brave to pull their guns and engage. If you are given all of one second to decide all of the listed factors, it is no wonder they did not shot well. But they survived the incident. The job is not for everyone and its complexity of late has become a real challenge. My 2 cents, Blue
