paint balls, snipers, land mines, all cost to much, that would cost the country just as much as letting them in. i would suggest a wall, with motion sensor machine guns. might cost a bit to install, but no paying guards a weakly salary. just someone to reload the guns. we would also benefit from the flock of wildlife our guns shot. we would have a constant supply of whateva type of animal romes the texas border. heh
