Yeah, like the guy who owns the place doesn’t consider it his own SHTF survival plan. If something happens, the doors lock and the claymores come out.
As another FReeper pointed out, I wouldn’t want to be anywhere near the place if something bad happens. Unless he’s got quality bars on the windows, locking the doors won’t matter. During the King riots in L.A., several armed men had to stand guard on the roof to prevent a firearms dealer from being looted.
