It has nothing to do with ethnicity and everything to do with importing criminals....like we don't have enough homegrown ones...and they get away with it because our government and law enforcement people haven't got the guts, or the will, to enforce our laws or control our borders.
So you are saying that all immigrants who are "imported' are criminals. I disagree with your thesis.
My contention is that you will always have bad apples, be they white, black, hispanic, asian, or polka dot.
