When the server comes up go read the bill. The review panel includes both parties, and can't be completely stuffed by design, and Posner will not take kindly to any attempt to make it proforma "no issue." It isn't as simple as "we object", being repeated ad nauseum, actual supporting evidence is required.
The key win apparently was the preemption, no more supermajorities required to improve the law and the various local laws, like Chicago's AWB, are gone.
Now the grind starts.
It actually reads like most of the first wave of "shall-issue" laws passed in the early '90s. Signage, high fees, lots of restricted places, etc. But those have fallen in a matter of years in most states, session by session.
The big two gripes are the review panel, which I think won't be as bad as it is being presented by folks (like me) who thought a clean bill would be passed; and the ban on carry on public transportation. The latter can probably be challenged on equal rights grounds using poor gun owners as front men, likewise the high permit fees.
The thing to keep in mind is that even though this law is a couple decades behind the current shall-issue status quo, IL is starting better than NY/NJ/MD or Cali and there is push-back even in those states about the anti-Dems trying to tighten their laws. The momentum is with the pro-carry side in IL.
