And that is the defining question, If I am to be disarmed by a property owner, it is then their duty to protect me when I am not armed... but me being me I don't leave my or my families security up to another individual.
Now I carry every single day, but when I worked for a couple of other companies, I made sure I got it in writing that the owner(s) did not allow weapons on their property and told my wife that should something happen, to pull out the documents and sue the living crap out of them until she owns the property/company.
Sadly, liability for refusing to permit carry isn’t established in the law and in fact is barred by statute in many states...
