66. FBI's Crime Lab

To spearhead its fight against crime and terrorism in the 21st century, the FBI is relying on its $150 million-plus building, the new Crime Lab at Quantico. Here, nearly 700 highly trained scientists and technicians utilize cutting-edge forensic technology to unearth identities of perpetrators. We review the lab’s history, from humble start in a lounge in 1932 to today’s state-of-the-art complex, and see how 9/11 and the FBI’s new mandate to fight international terrorism changed the lab forever.
