IAN: Good point, however, a possibility could be
(just speculation backed with no known research)
that our cities are more violence since they are
not homogenous cultures, that is, the U.S. is a
classic "melting pot," and urban communities in
the U.S. are quite often divided by voluntary
selection into ethnic areas. In areas with
multiple cultures, or "gangs," we tend to
see more aggression. Look at the problems
in India between Hindus, Muslims, and Sikhs,
look at Yugoslavia, look at East L.A.'s gangs.
But look a Japan, a monoculture with low crime.
