On Tuesday, acting Bureau of Alcohol, Tobacco, Firearms and Explosives Director Kenneth Melson was reassigned to a lower position inside the Department of Justice. How significant is this move to the ongoing Congressional probe into the government’s Mexican gun-smuggling operation known as “Fast and Furious”? What are the latest casualties connected to the guns the feds allowed to fall into the hands of violent criminals? Do we have any better idea of what Attorney General Eric Holder knew about this operation? How far along is the House probe led by Rep. Darrell Issa? We discuss these questions with Hans von Spakovsky, a former Justice Department official now with the Heritage Foundation. He also writes for Pajamas Media.
