The violent crime rate has fallen a third since the 1990s in spite of the recession. Why?
Was it leaded gasoline? Was it legalized abortion?
Have lower prices on Cocaine and Heroin reduced gang wars and profits? Are addicts now using cheaper drugs instead, like Meth, Marijuana, and Pharmaceuticals like Oxycontin?
Do government handouts reduce the desire to commit crime? Is urban planning making crime more difficult to commit? Is it better security systems? Do the mentally ill have better pharmaceuticals? Have the statistics been faked?
Was it more policemen? Was it better policing, like Rudy Giuliani did? Are there just less young people to commit crimes? Are criminals just kept in prison longer and off the streets? Are harsh prison sentences deterring criminals?
