I don't typically agree with this outlook, but I did give it some thought this morning after some facts came out. Put yourself in the officer's shoes however. This reportedly went down start to finish in less than a minute. You see this shithead run his vehicle into a crowd, hop out and start stabbing people. Are you sure that knife is all he has? Do you shoot to injure and hope he's not a suicide bomber, or keep pulling the trigger until you're certain that he's no longer a threat?
