Or all firearms are checked by cops before you get in the door with them. That coupled with the fact that I stopped believing in firearms that go off spontaneously when you clean them or set them down.
Something doesn't sound right here.
I don’t think cops do the checking here, if they are cops then they are off duty. I don’t see anything that makes cops more capable of checking a firearm than some other responsible person.
Only bad thing I’ve ever had happen at a gun show was when I had my wife with me. Got a Sieg Heil from one vendor and had another refuse to wait on me. My wife is Asian so they evidently had a problem with that.
