The ringleader of the rip crew that murdered U.S. Border Patrol Agent Brian Terry in 2010 received a slap on the wrist thanks to federal prosecutors in Arizona. The prosecutors asked that he only receive a 30 year prison sentence instead of a possible life term in prison or a possible death sentence.
Brian Terry, a member of an elite tactical unit, was killed on December 14, 2010, in a fierce firefight with a rip crew of gunmen who had been trying to rob Mexican drug traffickers. In the aftermath of the shootout authorities learned that some of the weapons used to kill Agent Terry were part of the infamous Fast and Furious operation. Under this operation the U.S. Bureau of Alcohol, Tobacco Firearms and Explosives (ATF) was allowing Mexican cartel members to purchase weapons in order to trace them to their source. Instead the agency lost thousands of weapons that fell into the hands of the Sinaloa Cartel.
