Concealed Carry

Wisconsin has begun debate on concealed carry again. But, unlike last time we now allow (or at least have ruled) extensive open carry. There are 2 competing bills. One would require a license the other would require nothing. As we all know there are 3 clauses in the 2nd Amendment and as far as I can tell the issue of licenses can't possibly be inferred from it. So, the correct bill is the one that allows concealed carry with no restrictions. One sheriff has gone on record as saying that we need licenses so that we now who is carrying. Doesn't that defeat one of the arguments that the NRA (who supports licenses, go figure) uses to fight gun control? The NRA believes that the Government can't know who has guns in case we start a revolution but yet they support allowing Government to know who is carrying a gun. I don't understand the sheriffs wanting to now who is carrying when these same sheriffs were all for open carry. If you are going to allow open carry without documentation why be restrictive on concealed carry? Of course, this gets us to the point of why do you need to concealed carry when you can open carry with no restrictions?
