Both Thirdpower and John Richardson are speaking about an assertion that’s appeared in the blogosphere that Illinois is now a Constitutional Carry state. I’d take anything you hear on the Internet (and I don’t exempt myself from this) as pretty much the polar opposite of actual legal advice. In other words, don’t think because a blogger says you can do X, that means it’s OK to actually go out and do it.
I try very hard to get things right, but firearms law is complex, and I’ve made my share of mistakes over the years. Even if you read blogs run by lawyers, they may be attorneys, but they aren’t your attorney. Do your own research, consult with your own counsel, and go from there. Our goal is to try to educate, and not to offer advice on whether a certain action may or may not get you arrested. Remember there are precious few petty offenses and misdemeanors when it comes to gun violations, and too many armchair “experts” out there to rely on what you see on the Internet.
