An article quoted the acting director that there will be legitimate citizens that will be "inadvertently" arrested. But that's because the local government and state have been resistant in reporting the "illegal immigrants."
So no, it's not "inadvertent." It's intentional to round up everyone first than ask questions for that person to prove they are citizens. So what if you're in a different state and your documents were confiscated so what can you use as your official document?
Gestapo, right?
