None of us think that cops are out to get us. Most recognize that the majority of law enforcement officers are just trying to do their job. But we are realists, we recognize that there is always a bad apple in a barrel. Someone who either is on a power kick or just does not know the law. Look at the average citizen, they think that you need a permit to carry a firearm. Law enforcement officers were once just an average citizen. So it is natural that we will run into a few bad ones. We always prepare for those.
Also, it does not matter if you know the cops by name and have had past (favorable) dealings with them. Look at all my stories, the only favorable encounter I had was with a deputy from a neighboring county. All the rest I knew, I played paintball a deputy for a while, worked wrecks beside the sheriff and have talked to all the other deputies for various things. Then I started carrying a firearm and they changed.
