One of the things that annoys me about the larger gun culture is the obsession with touching guns in the name of safety.
Our local gun show, the Indy 1500, is one of the larger ones in the nation. The line to get in often stretches around the building and right there at the front of the line, by the doors, is a big orange diamond-shaped sign like you'd find in a construction zone, reading "Unload Guns Here". No backstop. No clearing barrel. Just go 'head and clear your piece 'fore you go into the building, Cletus, so we can zip-tie it. For safety.
There is, of course, a corresponding pile of cut zip-ties by the exit door, where the Cletii have clipped them off in the foyer on the way out. Not much in the way of a backstop in there, either.
Now, given the generally appalling level of gun-handling prowess displayed inside, I can kind of see the logic behind the zip-ties; I mean, if you can't spot each and every one of the Four Rules being violated within ten feet of the front door, then it's time to trade the glasses in on a seeing eye dog, Stevie Wonder. (You have to wonder how much of that is a chicken-and-egg problem, though. Maybe all the Cletii inside feel comfortable wavin' their heaters around because, hey, they ain't loaded, buddy.)
But at the same time, I can't see how safety is enhanced by all the gun fondling around the entrance. I mean, every now and again, the law of averages is going to catch up with you.
(I haven't talked to anybody who was at the Evansville show yet, but from the wording of the article, it sounds like his negligent discharge occurred as he was loading up to leave.)
