Well, you might point out that there are two concealed carry bills that have been introduced and neither one currently has language requiring any particular training or course. The constitutional carry bill's only requirement is that a person can legally possess a firearm-- obviously there are other weapons besides firearms one might wish to carry concealed. The shall issue permit bill only requires passing a records check similar (probably identical) to the check one undergoes when purchasing a firearm through a licensed dealer.
So right now it would be as if I said "For $150 I'll give you a course that will allow you to eat ice cream cones." Your reply, "But I already can eat ice cream cones. I don't need your stinkin' course."
Now I don't see a problem with the people offering a course if they are upfront about it. They might want to offer a course that will enhance somebody's gun skills or knowledge of self-defense laws and discuss things like what to expect after a shooting, and so on. I could see where somebody who hasn't really given much prior thought to carrying a gun and who is unfamiliar with certain areas of the law might want to take a course of that nature now that they're suddenly entertaining the thought of carrying in a post-CC bill Wisconsin. (Of course it's difficult to teach a course about Wisconsin gun laws before the legislation that would drastically change them is actually passed.)
But they better not imply that such a course is mandatory or meeting some nonexistent requirement in order to carry. Unless something changes in the language of the bills, there will be no mandatory training.
