Stories like this are extremely prevalent these days, and certainly not the result of only one ethnic group. Not by a long shot. But it is an acute problem w/ illegal immigrants, and any attempt to deny this with anecdotal stories about other ass holes is superfluous.
Like they say in my neighborhood,
"How do you know you are in Koreatown?"
"Because all the Mexicans have car insurance."
Sorry, I'll do some volunteer work at my local La Raza office to atone for that.
