Correct, they're not trying to be accurate. They're using methods that they know to be inaccurate against minorities to get probable cause enough to arrest and deport them. If there's an issue, if they are wrong, if they violate someone's civil liberties so what? The point is deport them by any means necessary, because when they're gone they can't fight back. The Supreme Court said racial profiling is okay as long as it's done with some other factors. They are telegraphing as long as there is some amount of "process" even if it's theatre, racially profiling is fine as far as SCOTUS is concerned.
