Let's assume you're walking home at night and some seedy looking character starts following you. Let's say he starts talking very aggressively toward you like yelling, maybe even saying unpleasant things to, or plain not leaving you alone and just following silently, though not threatening you or physically touching you...yet surely he's following you and you know it.
If you pulled out the gun and said, "If you come any closer, I will shoot you," and he said "screw you," came closer, and you shot him, would that be justifiable self defense?
I guess what I'm asking is in situations that are common sense dangerous, but with no actual violence or threat of it yet, can you preemptively pull out a gun and "draw a line in the sand"? And if the person crosses the line, legally shoot him?I forgot to say that this question assumes a legal concealed carry license.
