America’s Real Criminal Element: Lead

In short: it appears that pumping vast amounts of a toxic heavy metal into the air might not have been a good idea. Numerous lines of evidence suggest that high leaded-gas use led, a generation later, to high crime rates; the reduction and elimination of leaded gas a generation ago led in part to the reduced crime rates seen today.

Not a really shocking hypothesis, but the correlations seem pretty convincing.
