Weapons lost during the Bureau of Alcohol, Tobacco and Firearms’ failed gun-smuggling project “Fast and Furious” will continue to show up at crime scenes on both sides of the Mexican border for "years to come,” Attorney General Eric Holder said on Thursday. Republican lawmakers at a House Judiciary Committee hearing pressed Holder to hold more officials accountable for the program. "If you don't get to the bottom of this [the one alternative] it’s called impeachment," said Rep. Jim Sensenbrenner of Wisconsin. Holder said top Justice officials did not know of “inappropriate tactics” until the boondoggle was made public, Fox News reported. In Operation “Fast and Furious” two guns lost after being sold to drug traffickers later showed up at the murder scene of a U.S. border agent.
