Then there's the issue of free speech. I'm no lawyer, but I can't imagine AOL being sued and beaten because of child molestation on its proprietary system. It'd be like suing the owner of a kiosk because I tacked a poster on it that charges you with beating your wife. I miss Simpson. The Democrats certainly suffered through 8 years of Reagan without impeaching him.
Public transportation is simply too inconvenient for most people to leave their cars.
It works in some situations, but so many people live so far out past Metrorail and most bus routes. Metrorail is very expensive to build on a per mile basis. A vast network of mini-buses in the suburbs would do it faster and better than anything else, I think. In general, I would disagree about demystifying alcohol and drugs. The more you make it available, the more you tempt otherwise solid kids into life-destroying situations.
