I know this my little bizarre point that no one cares about, but lead exposure probably didn't just create criminals, it also likely created a bunch of non-criminals who were complete assholes. I mean people prone to rage, to non-criminal violence like barfights and domestic violence (I'm not saying these can't or shouldn't be criminal, just that they aren't necessarily prosecuted), to doing things like stealing the houses of poor people just because you can. Also, too, should be criminal, but, you know, not.
