The guy was damaging/rampaging in the store and had an exposed gun, creating panic to the people around.
There are so many errors in your account that it's hard to even know where to begin.
1. There is no evidence that he was "damaging/rampaging" anything in the store. The Costco employee claimed that, but witness accounts say nothing more than he was placing water bottles in his cart.
2. He had a concealed carry license AND Nevada is an open carry state.
3. The only person that "panicked" was the Costco employee who didn't like the fact that he was carrying concealed. Other customers didn't think anything was wrong until the cops started shooting.
If he was carrying concealed noone should have seen a weapon. Also just because NV is open carry doesn’t mean
Costco is fine with it. I would not want to see people
openly carrying in my urban big box store either.
Its easy enough to get a concealed carry permit, so why do this?
Just to make a point?
I really want to see this COSTCO GFW on the witness stand.
