DBW, I think the idea here is my car is also my property. We're not talking about carrying in the building. And, like it or not, the Federal judge didn't issue an injunction based on property rights, rather based on a weak link he pulled out of a hat to OSHA.
Should your employer should be able to have an employment policy restricting you from smoking in your car?
Whose property are you placing your car on? Are you forced to park on their property? Do you have a right to tell someone else what to do with their property?
I know where you guys are coming from. But I simply don't believe that my rights trump someone else's right when it comes to my being on their property. A business owner has rights. It's his/her property. So when a business owner I work for or visit says "no guns", then I make the choice to comply or go elsewhere.
When the government (local, state or fed) tells you that you can not carry a concealed weapon on their premises do you comply or not? Government does not own anything... it belongs to the people. But you comply regardless. And as the SC has ruled in the past... government is no under any obligation to protect citizens. So you make the choice when you enter a government facility to check your guns and comply with the rules and hope that you'll be safe. Government, no matter what level... has no rights. Yet we comply with what they want.
My employer doesn't permit me to have a weapon in their property (in my case the truck they own that I drive). If I can't live with this policy then I can find an employer who doesn't have this policy or start my own company where I'm the boss.
