True Story - In the mid-80s, I was in a church service and heard a loud pop. My first thought was "Fire cracker"
But then there was a second pop and my next thought "That is not a fire-cracker". I pushed my family down beneath the pews and began to run toward the sound.
The story was that a lot of unarmed men all moved toward the fire to take the gun away from a Knot-Head. They did not hesitate.
The event ended well as the offender had taken a shot through his girl-friend's head for giving her heart to Christ, then turned the gun on himself. The bullet passed through her mouth from one cheek to the next, only hitting soft tissue. She was back a couple of week later telling us as how now she had perfect vision, something she lacked before. The shooter also recovered, having first giving himself a frontal lobotomy.
It is not my place to call the deputy a coward, but as a retired LEO, you move to eliminate the threat of deadly force, seek cover as necessary, but return fire. Otherwise, if you can't pull the trigger, then turn in your gun, you are worthless.
Thank you for your service and for your continued service.
