1. Any illegal immigrant who is arrested for a crime must automatically be charged with violating this country's immigration laws. Even if they are acquitted of the original charge that prompted their arrest, they should be deported.
2. No illegal immigrant can file a civil suit in the United States. In addition, any illegal immigrant who is involved in a civil suit as a defendant (if they are involved in a car accident, for example) must automatically forfeit any assets they have to the plaintiff in the case -- after which they will be subject to prosecution under the second part of Item #1.
3. Any illegal alien who is charged with multiple violent crimes will not be treated as a violent criminal in the United States court system. Instead, he or she will be considered a foreign combatant and subject to a U.S. military tribunal. Any nation that decides to "claim" this prisoner of war will first have to forfeit $1 million to the U.S. to compensate this country for its troubles. If no nation wished to "claim" this prisoner of war, he or she will be returned to their nation of origin via a U.S. military aircraft -- and dropped there from an elevation of 30,000 feet.
NOTE: Item #3 is the most pertinent, for it illustrates the real problem with the second sniper case. The problem wasn't that Lee Malvo was spared the death penalty -- the problem was that as an illegal alien he should never have been sitting in a U.S. court room in the first place. Someone who enters this country illegally and goes on a shooting spree is not a criminal -- he a f#cking invader.
