I know people who cruise gun shows buying broken guns really cheap, just to have them to “Turn In” at the next “Buy-Back” for $100.00 each!
I know one guy who “Antiqued” several Crossman .45 replica BB guns and even cap-guns, then got $100.00 each for them from the ignorant wretch manning the “Buy-Back” booth.
Sometimes “the people” win. ;-)
So do they check if any of them are stolen or maybe used in another crime? Sounds like an easy way to get rid of a murder weapon.
