So you thought only unauthorized immigrants are deported? Surprise - US citizens are sometimes shipped out of the US mistakenly. ICE officers often assume people are lying and mentally challenged individuals guilty of looking foreign and not being able to communicate well enough to overcome a stereotype. All good citizens carry a passport or birth certificate on them so these people are really asking for it, aren't they? </sarcasm off>.
I've blogged about Pedro Guzman before. Now his family is helping him to fight back. Good luck, Pedro.
