I meant those questions as rhetorical points to think about on this issue, I wasn't asking you to go out and find more information.
The most interesting issue for me is in what right people have to control their own property. You make a good point about keeping your property free from hazards but I think we have certainly seen this taken to an extreme where people sue for outrageous things so it cuts both ways. I am trying to envision what negative repercussions could come of this law. I support concealed carry but I am not going to jump on this bandwagon without thinking it through.
A business might also be concerned about liability if they let someone carry concealed and something bad happens so this could put them between a rock and a hard place.
1. People who legally carry concealed are not the threat.
2. Bad guys carry illegally. They will ignore the signs and bring their guns, especially if they know the rest of the place will be disarmed.
3. What kind of liability does the store face for not having metal detectors, armed guards, security cameras every 3 feet, doors that can be locked down if they see a problem approaching outside, or panic buttons to summon police? WHY ARE THE UNCONTROLLABLE ACTIONS OF LEGAL CONCEALED WEAPONS CARRIERS THE ONLY RISK YOU WORRY ABOUT?
4. Why is everyone not required to walk, take a cab, be dropped off by someone, or have a designated driver? Why are their car keys not confiscated upon entry so an employee can decide if the patron is sober to drive? Restaurants and bars have been sued for liability in over-intoxication leading to crashes and deaths on the road.
Carrying concealed doesn't lead to "bad things. It's usually the concealed carriers who stop the bad things before they get too far out of hand. If the place wants to protect the customers, they should hire a couple of cops to provide security if it's that rowdy of a place -- CCW or not!
There comes a point where you either treat all people as adults, or you close up shop because you can't trust everyone not to bankrupt you with liability lawsuits.
