On the Claim that Most of the Weapons Used by Criminals In Chicago Come from Indiana - https://www.washingtonpost.com/news/politics/wp/2017/11/07/where-the-guns-used-in-chicago-actually-came-from/

Yes, a significant number of the weapons confiscated in Chicago do arrive from Indiana (20%). That is a fact. But what's also a fact is that about twice as many of them (40%) had been purchased from Illinois gun shops, where the laws are much more stringent. And, besides, if gun laws are the determining factor relative to gun violence, shouldn't there be much more of that violence in Indiana? A reasonable question, no?
