Do people just as a matter of course exercising their 2nd amendment rights carry their weapon at the ready, as opposed to holstered or on a sling?

Everyone wants to hold the police to common sense decisions, but for some reason carrying a weapon throughout the store, which for all purposes in this case, looks real and is normally in a box, requires now not common sense on behalf of the citizen, but mind reading omnipotence on behalf of the cop.

Geez...
