bigyimmy,
I thought of that, but my post was getting a bit long, and I figured it would make my reply look like a flip-flop.
If an employer "doesn't ask", and the employee "doesn't tell', I guess nothing happens - as long as nothing happens. But if there is gunplay, bad things are almost guaranteed to happen, eh?
Many years ago a bar-owner customer of my father's lost his liquor license for running a "disorderly house". As I recall, it was a Friday night and one patron objected to another guy dancing to the juke box music the first guy had paid for. Words led to pushing & shoving. The dancing man fnally decked the first guy. The first guy left the bar, came back with a .38 and killed the second guy. Over a nickel!! (This was a LONG time ago.)
To make a long story short, the bartender called the police. The bar owner got his place closed down by the PA Liquor Board, and the killer served a couple of years.
So, bad things can happen that are way beyond your control, but not your liability.
