The supreme court screwed us when they made the "Reasonably safe" judgement to business. Which means they can prohibit you from carrying a weapon on company property, as well as deny a lawsuit if you get hurt because they don't protect you while unarmed. Total BS
Depends upon the law of the state. Here, if I have my permit to carry, I am legally allowed to exit the vehicle and place it in my trunk while in the parking lot. Schools, churches, gov't property, businesses with strict no carry rules all are the same.
In regards to the lawsuit if you're inured/robbed/etc while on property which doesn't allow you to carry, you can sue the place. You may or may not win. However, I know of two companies whom have been sued, and lost, when it came to failure to protect it's employees. One woman was killed by her ex while in the parking ramp going to her car after work. Company was found negligent to protect her.
What is one of the countries with the lowest crime rate? Sweden, where every man of military age is required to have a gun in the house.
Yep. Switzerland, they keep their issued rifles for life.
