How interesting; I was not aware that the permit conferred any special privileges anymore. Neat, thanks!
The main thing being reciprocity with other states.
Few if any, accept AZ, AK, or VT residency as your "permit".
Assuming the elections go well, and WI FINALLY gets shall-issue CCW sometime in 2011, I hope the signage requirements are like they are in other versions of the bill that had come up.
Monkeyleg might be able to fill in more details, but I think the bill required a sign of a certain size and format (anti-gun forces wanted 8 1/2"x11" so they could fax/mail every business in WI a sign should it have passed) however, a reading of the bill seemed to indicate that the signs only had the "trespass authority", meaning, if you carried in violation of the sign, you still had to be
noticed carrying, and
be instructed to leave, and were then only in legal peril of misdemeanor trespass if you were so hard-headed that you
still refused to leave.
My read of the whole thing was that it's a wink-and-a-nod to the "concealed means concealed" part of CCW.
The one upside of going shall-issue second-to-last here in the U.S. is that the pro-gun drafters of the bill can learn from all the tricks and roadblocks, and poison-pills that all the other CCW states have had to deal with already.
