As another poster has pointed out, Wisconsin has no concealed carry law. I believe that they managed to add a right to keep and bear arms to their state constitution just in 1998.
Similarly, Kalifornia has a "may issue" concealed carry law which means that the majority of citizens will not be granted a permit. The only legal carry otherwise is open and unloaded. There are groups exercising this very limited "right".
In the early days of the Republic, the common perception was that only a criminal would conceal his weapon. I think several states have RKBA in their constitutions but specifically exclude concealed carry. Your attitude toward open carry is a prejudice. Why would you fear the open carrying of a firearm by me any more than you would fear the open carrying of a firearm by a uniformed policeman? Don't you think that most criminals would rather hide their intentions until they attack? What advantage would a criminal get by carrying openly?
Dad was a cop, grew up with guns, don't have any prejudice toward them, have a couple of my own....if you read *fear* in my response, you read it wrong...
I have always been around guns, nothing to fear, my family are all hunters with both gun and bow and arrow...Hubby had quite a few. Sorry that you mistook my response as fear..
