well... the drug flow from mexico to the U.S. WILL NOT STOP. its a multi billion dollar a year biz for these guys... they will always be one step ahead... if tons of cocaine can make it here, we will always have illegals.. its a no win battle.. only way to stop it is to shoot them on site when attempting to cross... and even then... theres hundreds of tunnels at the border with new ones getting dug everyday. US should legalize all drugs. ppl are gonna do them no matter what.... then we have no use for mexico.
