Illinois is looking to New York as their guide to conceal carry. In New York, counties are in charge of issuing the permits, and they can be very restrictive. The biggest restriction is the need to prove that you "need" a gun.
This restriction doesn't seem to be in accordance to the second amendment to me. What other natural rights does the government allow you to have only if you can prove that you need them?
New York counties can also restrict those gun rights in other ways. My buddy has a permit, but the judge restricted its use so that he can only carry from his home to the range. I thought that that was pretty blatantly illegal, but from the article it turns out that that restriction is commonplace.
A system like New York's is obviously a huge improvement over what Illinois had, and I am sure that in rural counties it would be similar to what we have here in Indiana. Maybe that's the best they're going to get over there.
