This question reminds me of one I have always wondered about.
Do you carry all of the time regardless of the rules & laws involved?
The bad guy doesn't care. He will pick his time and place to do his deed - maybe with the idea of being in a "no gun" zone adding to his decision.
"Concealed Carry" means just that - if it is done right no one knows, except you. So, if nothing goes down, you're in & out without anyone the wiser.
But, if the bad guy(s) decide to ruin your day, and you followed "the rules" you're up the creek without a paddle. If you break the rules/law at least you stand a fighting chance and hopefully, will be able to argue your way through the legal system.
