"I used to be a police officer. I’ve held a gun aimed at a dangerous offenders head and had to choose whether or not to pull the trigger."

Wait, what?
It may well have been a situation where the person was presenting a threat to others and he had to decide how to how much threat was being presented and how to prevent that.
But even so, should police officers really aim for the head?
That's a good question.
It obliterated the little anecdotical nuggets remotely interesting in the writing.
