Posted by fallout mike: It's not at all a question of whether he is homeless. The issue revolves around his allegedly carrying a knife in his hand. Did he constitute an imminent threat? That would depend a lot on the distance. Judgment call, but if you see fit to move your cover garment and put your hand on your gun, you had better call them--right away. That's not the way I read it. Absent lawful justification, that is sufficient to constitute a crime.
