Dear Chemist_Geek,
I think that plaintiffs in a case like this would make the argument that if you freely permit firearms into the workplace, given enough folks in the workplace, it is foreseeable that someone might lose it and "go postal," if for no other reason than - IT HAPPENS.
Whether I personally would accept the argument, heck, whether I could even adequately MAKE the argument (I'm not sure I could), is irrelevant.
I'm sure that, say, John Edwards would do a fine job with the argument, and given 12 dunces, could secure an eight figure verdict.
As a business owner, that's the question I ask - not whether something is right or wrong, but how well I'd be able to defend it in court.

That's correct - you have to pay attention only to your fiduciary responsibility to the company, and enacting or failing to enact certain HR policies is begging for trouble.
