Sandy Banks notes today that crime rates in Los Angeles are way, way down:
The reasons are complicated and ripe for debate: better policing and more community involvement; fewer drugs and fuller prisons; an explosion in new technology; and the fading profile of violent gangs.
The phenomenon ought to be scrutinized. We need to know what mix of forces has conspired to drive crime down, so we can — in an era of shrinking resources — plan and spend wisely to keep this going.
Don't forget lead! Lead lead lead lead. When is the connection between reduced lead levels and reduced crime levels finally going to penetrate the minds of American journalists? I know it's not sexy and I know everyone wants to ignore it because you can't tell heroic stories about lead, but it's almost certainly the single biggest contributor to crime reductions nationwide.
Plus it's good news: the fact that reduced lead levels have played a big role in this means that a lot of the decline in crime is permanent. Hooray! Get rid of even more lead, as well as other environmental neurotoxins that affect small children, and crime levels will come down even more. Double hooray!
