Given the information you've presented, were I in that position, I would have drawn. Now, whether I would have fired or not depends on their reaction after I displayed my firearm. If they backed off, then I would just call the police (though I'd stay unholstered and at the ready). If not, then I'd shoot until the threat was stopped and then I'd call the police.
I am making a few assumptions here, of course. No provocation, nothing illegal or threatening regarding your actions, etc. If there are different facts not listed here, well, my opinion could change.

I'm not eager to shoot someone but this fellow may have very well had two, three, or more smoking holes in him depending on just what RottenApple said above and I would worry about the Grand Jury later. One way or the other he would still be there when the police arrived. With or without said holes in him would be entirely up to him.
