Thanks, but why don't you piss of instead?

Also by the time you see a gun, it's already too late. Have you thought about a second, maybe?

If a person has the intention to shoot a police officer, he wont hesitate to do so. Maybe that's why they don't like to wait until they see a gun? Or do you think the raging person will ask politely first, if he can shoot at them or not?

Maybe you should think about both sides in a situation? Maybe understand how a situation can escalate quickly into a shooting spree? And maybe that's the reason why officers don't risk it at all and rather shoot first?

At the end of the day, they are people too. If you can't understand that then why don't you go and be a police officer and show us idiots how it's done.
