So Wisconsin doesn't have a firearm preemption law???
I thought that if you post a sign you assume responsibility for any act against someone?
No. The law says if they don't post, they are immune to liability from that decision. That's it.
I suspect in order to "win" a liability claim against a posted business, one would have to:
- be injured in such posted place....
- survive...
- show that they would have been carrying at that particular time, but for the sign
- show that it was likely that carrying would have prevented the injury.
- probably more.
Suppose someone followed you in and shot you in the back. It would be very difficult to cast blame on the biz for that.
