Violence and "crazy" people tend to be clustered in certain areas and not spread generally among the populace. For example, I bought a house in a "genteel" part of a mill town. In other words, the houses are maintained. 2 miles away in the "mill worker" section of town (not very well maintained housing) we've had numerous reports of violence, and one or two murders. I can go to my local supermarket, Home Depot, drugstore, ice cream stand and never encounter any violence. Travel on the bus however and well, the police reports say it's a different story. With the reality? Not sure but every time of been on public transit, it's a cluster of "crazies" mixed in with the general populace. What this tells me is the problem is not public transit or urban spaces. We need to build a more humane city like what they have in Scandinavia (high public trust, services to keep you from being desperate, respect for common individual property) and the risk of violence will drop both in city spaces and on public transit.
