Inside The FBI Terrorist Explosive Device Analytical Center

An "Evidence Do Not Touch" sign sits on top of a package containing improvised explosive device (IED) evidence from Afghanistan at the Federal Bureau of Investigation's Terrorist Explosive Device Analytical Center (TEDAC) facility in Quantico, Virginia, U.S., on Monday, April 21, 2014. TEDAC was formally established in 2003 to serve as the single interagency organization to receive, fully analyze, and exploit all terrorist improvised explosive devices, or IEDs, of interest to the United States. To date, TEDAC has received tens of thousands of IED submissions, primarily from Iraq and Afghanistan. Photographer: Andrew Harrer/Bloomberg via Getty Images
