HR 4437, the Sensenbrenner bill, makes it a felony to be in the United States without proper documents and makes it a crime for anyone to aid undocumented immigrants.

Question: if I encounter an illegal immigrant in the desert in need of water or food or medical assistance, and I help that person, am I guilty of aiding and abetting a felon? Should I do jail time? Or should they just die?
