when is it "ok"?

[gregarat]

At work, even off duty. If someone brandishes a gun, electronic weapon or device, tear gas gun, knife and billie, within nine feet of me. I will shoot them in the chest. I will also shoot to protect myself or another person from death or serious bodily harm, trying to prevent a forcible felony (such as rape, robbery, burglary or kidnapping).
By Florida law I cannot give a warning shot, or shoot to wound. At work I cannot cock the hammer for a single action shot, double action only.

I might get some "wiggle room" at work, cause my work place is covered under the Castle Doctrine.

But like Andy said, I can probably expect a law suite. Covering my behind is extremely important at work.
