If we could be assured that they will never enter this country again, I suggest we skip the jail time and deport them immediately. They managed to get in here because our government has blatantly broken the laws already in place. Law-abiding taxpayers rightfully have no obligation to foot the bill to keep these foreigners in our prisons.
I can just hear the buzz this would create. "Hey, let's go to America and commit some crime. Even if we get caught, all they'll do is ship us back".
