When you hear about this or that business being robbed and the security guard fighting off the attackers, you tend to think that it was a dangerous risk to take. But I started to wonder: what is a security guard for, if not to do exactly that? Any of us can roll over, get on the ground and say "take what you want, insurance will cover it", and if the security guard does so too, then he might as we,ll be one of us. Granted, there are lower-risk threats that they protect against, and you have to draw the line somewhere, but a couple of idiots with cricket bats are probably below that line for a paid security guard.
