Proponents of stricter gun controls say that the staggering numbers of U.S. weapons that end up in Mexico show that something must be done to control arms smuggling."
But it could be said this is precisely what the current administration wants to happen in order to be able to pass more laws banning firearms. Back in February, CBS Evening News was one of the few media outlets to report on Project Gunrunner, a project that seemed to allow large numbers of firearms to cross the border into Mexico despite protests from ATF agents.
"For months, ATF agents followed 50-caliber Barrett rifles and other guns believed to be heading for the Mexican border, but were ordered to let them go. One distraught agent was often overheard on ATF radios begging and pleading to be allowed to intercept transports. The answer: "Negative. Stand down."
According to the CBS article, two of the guns allowed to walk were found at the scene where Border Patrol Agent Brian Terry was murdered, and despite arrests for the guns themselves, no further mention has been made of the murder.
Theories will vary wildly, but it would seem the government is purposely allowing guns to cross into Mexico to "prove" that the illegal gun trade is a problem in order to garner support for more gun laws, rather than consistently enforcing the ones already in existence."
