Jiro,
i was in Richmond, CA (when i was young kid with my family who live there for just temporary before we moved to Fremont) when there were greatest gangester trading place as known as "Trading Bay", there are Vallejo, Concord, SF, Oakland, San Pablo, Daly City and Petulma areas that comes in Richmond to make the trade: drugs, weapons, girls, and illegal things which cops will bust everyday. IF IF i saw the trading attempt, they dont give a f..k about it and just shoot at me, chase me down n beat me up, or threat me n my family. That is one of dangerous city in 1990's.
Experts say 'most dangerous city' rankings twist numbers - CNN.com
as you can see that: #9- Richmond, California.
we are not safe in everywhere, anyway.
