I know he had a break in before and I think it was at his old location, though I'm not certain.
Security door/window bars may not keep everyone out but would probably help prevent this sort of low-level smash and grab from happening. With that said, those sorts of things aren't cheap.
Hopefully these little shits are caught and the guns returned. I'm still not sure what all was taken but I can only imagine this would leave a pretty big dent in their bottom line. We only have 2 airsoft stores in the entire province for god sakes, we can't afford to lose any.
