You misunderstood my post so let me rephrase for you, I means ICE agents are getting deal with illegal immigrants, same word for taking care, such as arrest, deportation, court, detention, etc.
Polices are supposed to focus on crime that anyone commit but not any illegal immigrants whoever haven't commit crime yet so it is waste for them to do job since ICE agents is responsible to crack on illegal immigrants since police will do if it is secondary case after suspect of crime.
Illegal immigrants aren't crime but more civil issue so they are punishable by federal immigrant law, of course.
Last paragraph, I already know that ICE is part of federal agency so I'm not dumb about anything so DUH!!!!
