This is incorrect reasoning, because there may be other differences
between Chicago and DuPage county. To do the test properly you would
have to find two areas that had similar demographics but differed only
in gun accessibility.
(Yes, I am aware that such studies have been done, and that people differ
in interpreting the results. I don't want to get into that debate.
I just wanted to point out that this particular line of reasoning
involving these two locations is not correct.)
