I'm sure Dick or GnL could probably explain this better than me, but I'll give it a whirl...
I think everyone's goal (at least the true, freedom-loving folk I know) is to have "Vermont-style" carry here in WI and MN for that matter. Part of the situation is that some of us have been waiting for these court cases to deliver the death blow to the carrying concealed prohibition. Remember that, technically, WI is an already an open-carry state.
I think anyone involved in getting the CCW bill passed the last time around has been doing it as another option to the court cases. The thinking being here is that since our rights were taken away incrementally, we have to win them back incrementally.
That's just my take on it. I could be totally wrong.
Believe me if I had my way, there wouldn't be any restrictions on carrying open or concealed.
