24-year-old Efraim E. Diveroli, who scored a $300 million weapons deal with the Pentagon for Afghanistan in 2007 and was eventually charged with ripping them off, is at it again, trying to purchase guns for "resale in the Miami area."

Diveroli's old company, AEY Inc., was awarded the contract three years ago to supply ammunition and weapons from former Eastern Bloc countries, but was arrested and charged after slapping new labels on boxes of Chinese munitions made in the 1960s and other amazing scams. A New York Times investigation lead to his indictment and eventually, a plea agreement on a conspiracy charge. So what did Diveroli do while awaiting sentencing? He got back into the game!

On Friday, Diveroli was arrested again after falling into an undercover sting operation set up by agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives, one of which he told: "Once a gun runner, always a gun runner." After being impressed by the undercover agents' guns, Diveroli walked into a Wal-Mart to buy ammo to go shooting. He was arrested in his Audi.
