Several decades ago, I saw a LEO friend and another cop using their vehicle as a barricade with shotguns pointed toward a closed bank.
I was carrying then and NOT a LEO. Besides that, I saw my friend and thought he might want some help. I stopped the vehicle, rolled the window down and asked if he needed help.
He said no as they were just conducting some training. I said goodbye and drove off.
About a week or so later, he thanked me for stopping and said it was comforting to know that their are people out there that would stop to help like that.
Would I do that today? Only if I knew the cop and he were a friend. I don't fear getting shot at by a bad guy as much as facing liability, or criminal charges, for helping a cop who might be using excessive force or targeting a good guy.
I back the blue as long as they support my 2A rights. If not, piss on them and stick their badge up their ass.
