On the other hand, the lack of armed response from these artistic cowboys seems odd by a conventional mindset... I wonder if the fellow was surprised that he didn’t provoke prompt gunplay. Even though, reviewing the circumstances, we aren’t surprised.
Assuming guns were allowed into the concert area (I strongly doubt it); what exactly do you think they could have shot at with a handgun? Could they see where it was coming from? Not from what I heard. Even so; it would have been far out of range for a handgun. It would have been reckless to try.
I’m thinking the night vision goggles and AR’s/AK’s were left at home on concert night.
