Your first MotherJones link seems a bit inaccurate… Try this one
I was about to post on this subject myself to see if there were any LessWrong opinions. It’s certainly more than just one US-wide correlation; similar correlations appear at the level of individual states and cities, and internationally too. Plus there are longitudinal studies (following cohorts of children with different measured lead exposures through time, and monitoring levels of school delinquency then criminality).

Oh goddamit… thanks for catching the bad link. Fixed.
