Interesting discussion no doubt but I have a question. Virtually every gun store I have ever been to has a sign on the door stating that ALL firearms must be unloaded and cased BEFORE entering. This isn't Target or Costco, we are talking your local gun shop. If you are legally carrying concealed do you comply? Given all the comments about merchants that do/don't have the right to restrict carry and the various political agendas associated with each side of the argument how do we reconcile the gun shops putting this restriction in place???
