No alarm on door? No motion sensor on door?

Seemed like the yute were organized, in and out.

Shutting down for the night? A length of coated stranded metal clothesline with a loop on each end, threaded through the trigger guards and table legs and loops locked together would have made this theft difficult enough they would have moved on.

If all dealers present had done that, the perps may have been thwarted (time element).

If FFL dealers, they should have make, model, and S/N for the arms, but that doesn't put stock on the table during the show, either.
