Tom I'm not an armed officer, I wouldn't know a trigger from a firing pin, but I know enough to leave it to the specialists. As you quite rightly say, they are villified when they pull the trigger, yet their training is geared towards using lethal force as a final option. They all know that shooting someone will result in a massive investigation and they will be subject of the hindsight brigade's pontifications. Thank you for putting your point of view, it's nice to know there is some support out there.
