The Energy Department's assistant inspector general, Sandra D. Bruce, said her office reviewed 16 alcohol-related incidents involving agents, candidate-agents and others from the government's Office of Secure Transportation between 2007 through 2009. Nearly 600 federal agents ship nuclear weapons, weapon components and special nuclear material across the U.S.

Two incidents in particular raised red flags, the report said, because they happened during secure transportation missions while agents checked into local hotels while on extended missions. In these cases, the vehicles were placed in "safe harbor," meaning they were moved to secure locations. [ YAHOO NEWS ]
