Interestingly, most ended up in the area around Hunter's Point just south of San Fran. This was a lower income area infested with Black gangs. The Marine gate guards at that shipyard regularly engaged in firefights with the locals. It was a crime ridden zone. The Vietnamese came in, and the Blacks saw them as easy pickings. The Vietnamese were like, We just survived 20 plus years of war and communism. You are nothing compared to that... and they proceeded to wipe out the Black gangs in short order with their own organized crime groups. The area is far safer today than back then.
