I dont understand what you mean by your comment. He was arrested for being in the country illegally. The way this is supposed to work is: 1) you get a warrant, 2) then you make the arrest, and 3) the person gets due process in court. We finished 2 and we definitely need 3. If we dont we have a problem. But what they did so far was correct.
He also was in court for battery. It seems like you're implying that since battery is not illegal entry that he couldn't be arrested. ??? If anything thats just another good reason not to aid his unlawful presence in the country.
