My posting a possible ‘reason’ WHY the gun sock, coat and ‘open carrying’ in the store is just that - a possible explanation.
Further, ‘open carrying’ a gun/rifle like that (i.e., attempt to conceal for whatever reason) could be construed (by some leftist LE/DA) as concealed-carry and many state open-carry laws don’t cover that unless there is a concealed carry license. I know there’s a difference wrt that in my state.
You can take the laws for what they are, stupid or not, but there they are...
Gangsters like this one are not concerned with how some leftist might interpret the law.
