In Ohio, part of the CCW law was that any place could post a No Guns Allowed sign and violating the sign was a crime. It also stated that places could not be sued based upon the decision to allow or disallow firearms there.
I don't know if the law has been tested, but just because it is a law, there is no guarantee it will work.
I like half the law. It is fine that the place can't be sued for someones misuse of a firearm on the premise but they should be responsible for removing the person's right to self defense.
TAB, in one of your posts, you state that "Chances are very good, if you had no chance with out a gun, you would have had no chance with one."
Can I assume from that statement that you don't carry a weapon as it would be useless?
