I will add that we want them frankly, to take some risks, the kill rate for innocents and unarmed people is getting out of hand high, they can't continue this rate of killing us just to play it safe.
When the criminal is telling the officer that he has a gun and is going to shoot him, then he is begging to be shot. If you are that stupid then Dawin’s law needs to be applied.
Two years ago I was in a similar situation. This druggie charged me. He is lucky to be alive. While I did not pull the trigger, I was very, very close. He he had not stopped when he did, I would have shot him. My heart is pounding just remembering the situation. My CCW instructor was amazed when I told him about it.
