Here's an analogy, which relates to the question of aliens’ rights and mass immigration of the last thirty years.
Some years ago, a friend of mine was objecting to the activities of the Guardian Angels in a certain neighborhood, which housed, among other things, the local lunatic asylum. He said that the Angels were trying to prevent prostitutes, drug addicts and mental cases from harassing the citizens. They were overlooking the fact that in this neighborhood, for practical purposes, prostitutes, drug addicts and mental cases were the citizens.
Raul Grijalva seems to feel that Arizona is that kind of neighborhood, and that police should let his illegal compadres alone.
