A perfect ten is a great score, unless you’re the Governmental Accountability Office and you’re talking about how many times you were able to smuggle bomb-making materials into so-called high-security federal buildings. The GAO released a report yesterday documenting their study: not only were they able to get the bomb-making materials into the buildings, they were also able to walk around the buildings undetected. Joining The Takeaway to discuss this disturbing report is Mark Goldstein, director of physical infrastructure issues at the U.S. G.A.O., who led this investigation. Also joining the conversation is security strategist J.R. Roberts.
