Crowding is only part of the problem in big cities.  Some local
experiences have shown that the experience of "neighborhoods" and being
part of a small enough social unit to personally know the people who
might otherwise be your victims makes a big difference in the amount of
violent crime.  Many street criminals have no sensation of the other
person's pain in response to the crime.
