Hey bone, I like how you think but this problem demands a multi-pronged approach. Firstly, take the $4Billion in aid to Mexico and reduce it by $10K per alien detained within 100 miles of the border. $100K for each smuggler (dope or human). Mexico would lock the border down from their side over night instead of distributing leaflets instructing crossers on topics like, surviving in the desert and how to avoid U.S. Border Patrol and other Law Enforcement entities. With a couple hundred thousand apprehensions a year in Tucson Sector alone, that $4B would be eaten up pretty fast. One thing the Mexican government loves and needs is the U.S. Dollar.
