Guns seized from the Mexican Sinaloa cartel during "Operation Pipeline Express" are displayed at a news conference in Phoenix, Arizona October 31, 2011. Law enforcement authorities have arrested over 70 people in raids that dismantled a narcotics trafficking network suspected of smuggling nearly $2 billion worth of drugs through Arizona's western desert, officials said on Monday. The announcement in Phoenix caps a 17-month investigation culminating in a series of three "large-scale enforcement actions" tied to the probe, according to U.S. Immigration and Customs Enforcement, the Arizona Attorney General's Office and the Pinal County Sheriff's Department.
