I expect that The Usual Suspect States (NY, CT, IL, CA, etc.) will create "objective" standards for issuing licenses, but those standards will be so stringent as to put them out of reach for a lot of people.
I don't think the Illinois politicians have much appetite for another 2nd Amendment fight. They know that its a losing battle and they're content to let sleeping dogs lie.
It is also interesting to see that much of what Judge Posner said in Moore v. Madigan shows up in the majority opinion of NY State Rifle & Pistol Association v Bruen. The Moore v. Madigan ruling threw out the provision of the Illinois Unlawful Use of a Weapon law which made it illegal to have a firearm on your person ouside of your home or personally owned business. The ruling in Moore v. Madigan gave rise to the Illinois Firearm Concealed Carry Act which is a shall-issue law. There was much debate at the time from the most rabid gun-grabbers that Illinois should enact a may-issue law, but the majority of the Democrats saw the writing on the wall and didn't think a may-issue law would withstand scrutiny for long (and they were right )
I believe that the Illinois carry law is unconstitutional based on the14th Amendment, and I think it will be challenged. The Illinois Firearm Concealed Carry Act prohibits people from carrying on public transportation, but crime statistics show that public transportation is extremely dangerous. People using the CTA in Chicago have more of a need for a firearm for self-defense than people just walking down the street. People just walking on the sidewalk, driving their car or riding a bike are able to exercise their Second Amendment rights, but people who utilize the CTA are not able to exercise their Second Amendment rights.
That seems like unequal protection under the law to me...
