There were around 2000 border guards in the Mexico-America border, before 2006. They used equipments such as FLIR, infrared devices, helicopters, M-16s, Desert Eagles and Steyr AUGs, to stop anyone from crossing the borders illegally. Many people think that only around 100 soldiers with these equipments could make it impossible to cross the 3169km border. But on May 5th 2006, 16 vans carrying drugs crossed the border illegally, without getting caught. George Bush sent in 6000 National Guards to help the boarder.
