I don’t see what the big deal is about open carry. I’d sooner ban concealed carry and allow open carry so that everyone knows where everyone stands. I’m certain that many people carrying concealed ignore “Firearms not allowed on these premises.” signs. Not possible with open carry.
Open carry seems to make even concealed carry advocates leery.
Personally, if I’m in a situation where a group is confronted by an armed gunman, I’m all for open carry. One of the two people openly carrying will likely be dead and that’s likely to be the end of it.
Open carry attracts the attention of cops, nuts and criminals. More for them, less for me.
