It is also the individual’s to determine when/where to carry.
Correct, but yet you impose your own determination on others: “I don’t understand why anyone would carry open, at a family festival event, with so mny people in close proximity to each other. Having both hands pre-occupied, lends itself to having one’s weapon easily taken. Regardless of the lagality, I think it was a pretty irresponsible thing to do.”
So tell me, what constitutes close proximity? 10 feet, 20 feet, 30 feet?
