From Chris Truax:

So is getting immigrant criminals off the street a justification for ICE’s behavior? Constitution says no. Of course, some immigrants are criminals who shouldn’t be on the streets. Some Americans are criminals who shouldn’t be on the streets either. Nonetheless, we have a Constitution that prevents police from roving those streets and demanding that people present their papers, or from breaking into someone’s house without probable cause and a warrant signed by a judge. Those rights don’t exist to protect criminals. They exist to protect innocent people. And it is innocent people who suffer when those rights are ignored, whether the government is hunting criminals or immigrants.

Concise, well written breakdown of what’s at stake here. No notes.
