I say we solve this while satisfying our PC fetish. Put a sign up every 10 feet that says "This is provate property of the united states of america, and any tresspassors will be shot". Then when they sneak in, SHOOT THEM! They come into our country illegally, they do so at their own risk, and it should then be LEGAL for any US citizen to kill any illegal immigrant so long as he can prove they are illegal, and do so not in cold blood, but to protect our country (The intent can be proved by whether or not anything is taken from the dead alien, or whether the body is disturbed in any way other than it having been shot). Thats how I say we do it.
