Possession of a stolen shotgun does in fact make you an offender.
I don't personally research each used weapon I purchase, but, my affirmative defense is that I use an FFL and I have a reasonable expectation that if it passes through his hands it isn't hot.
Hanging with criminals isn't a capital offense, pointing your weapon at a police officer screaming "POLICE, POLICE, SERVING A SEARCH WARRANT" can be and should be.
The problem is that you are Monday morning QBing through an anti police prism
Cops lied. Guy dropped his bible when jackbooted thugs threatened his bunny and he tried to reason with them and he was FORCED to commit aggravated assault against a Police Officer.
