I’ll let the lawyers weigh in on this one as to the legal ramifications of what this fellow did. Readers can weight in too, but I wanted to focus on whether this was wise (h/t Uncle).
There is an interesting discussion here about this. My take is that a mob, or any potential assailant for that matter, can close the gap very quickly. I don’t fault the man for unholstering his weapon. Neither do I fault him for walking backwards and very carefully while trying to pay attention to his surroundings.
What I would say though is that if he thought he was under threat, when he was out of range he should have retreated and gotten away. I would have. Remember, egress, evasion and escape. That he came back will probably be a problem with a prosecutor.
