From Steve Sailer's post on the possible link between less lead in our environment and a drop in crime:
My impression is that popular culture today has gotten rather authoritarian or militaristic. Cops used to be portrayed as big dumb Irishmen, easy to outwit. But now, they're portrayed as practically Seal Team 6, with lots of cool weapons and training. Authority has most of the glamor these days, while criminals seem like losers.
We're a bit early for it yet, but the early Empire is quite popular after the time of troubles.
