Something a lot of people don't seem to realize...

"If one group doesn't get due process, nobody does" is not just a slogan, it's a simple fact.

If illegal immigrants don't get a chance to at least argue they are in fact allowed to be in the country before getting deported, then neither do you if a cop calls you one because he doesn't like your face.

There's a good reason the constitution explicitly grants due process to persons and not just citizens. This is that reason.
