Secret Lab Keeps Eye out on Potential Syrian Bombers

OUR PENTAGON CORRESPONDENT BARBARA STARR WITH THE EXCLUSIVE. >> Reporter: CNN'S CAMERAS ARE THE FIRST EVER ALLOWED INSIDE THIS WAREHOUSE. THE LOCATION IS SO SECRET, WE'VE AGREED TO ONLY SAY WE ARE SOMEWHERE OUTSIDE OF WASHINGTON, D.C. THIS IS JUST PART OF 100,000 PIECES OF EVIDENCE FROM TERRORIST BOMBINGS IN 25 COUNTRIES. ANALYSTS HERE LOOKING AT EVERY BOMB FRAGMENT FOR CLUES TO A BOMBER'S IDENTITY AND BOMB DESIGN. BOMBS FROM BOSTON TO THE ATTEMPTED UNDERWEAR BOMBING OF AN AIRLINER TO IED ATTACKS IN IRAQ AND AFGHANISTAN HAVE ALL BEEN ANALYZED HERE. >> SO WHEREVER THEY'RE COLLECTED. IF A BOMB GOES OFF, WE WOULD LIKE TO SEE THEM, NO MATTER WHERE IT IS AROUND THE WORLD. >> Reporter: THIS MAN RUNS THE ANALYTICAL CENTER, AMERICA'S BOMB LAB. BOMBS FROM NEW FRONT LINES COME HERE. YEMEN? >> YES, OF COURSE. >> Reporter: ANYTHING FROM SYRIA YET? >> I DON'T WANT TO DISCUSS INDIVIDUAL COUNTRIES. >> Reporter: BUT THE LATEST WORRY IS THE THREAT OF ATTACKS IN ROW TAL YAGS FOR A U.S. STRIKE ON SYRIA. >> WITHOUT QUESTION, THAT'S A CONCERN. >> Reporter: YOU HAVE ALREADY TAKEN A LOOK AT THE SUPPLY NETWORKS IN THE MIDDLE EAST. YOU KNOW WHAT'S OUT THERE. YOU KNOW WHO THE BOMB-MAKERS MAY BE. >> WE HAVE A GOOD IDEA. >> Reporter: EVERY DAY, THE LAB ANALYZES IEDS FROM THE WAR ZONE. THIS BOX ARRIVED JUST 48 HOURS EARLIER FROM AFGHANISTAN. THE WIRES, THE PRESSURE PLATE, IT'S ALL HERE. THEN THERE WAS BOSTON. WITHIN HOURS OF THE ATTACK ON THE BOSTON MARATHON, COMPONENTS OF THE BOMBS ARRIVED VERY QUICKLY HERE AT THE LAB. AND EXPLOSIVE RESIDUE WAS TESTED RIGHT HERE. HERE IS THE EVIDENCE FROM THE UNDERWEAR BOMBER. AFTER ANALYZING IT, THE LAB QUICKLY WARNED THIS WAS A BOMB WITH NO METAL PARTS, HARD TO DETECT AT AIRPORTS. FOR THE FIRST TIME, YOU SEE FINGERPRINT TECHNICIANS, SCOURED PHONE PARTS. FOOD REMNANTS. >> HOW OFTEN ARE YOU ABLE TO RECOVER A PRINT THAT'S GOOD ENOUGH TO LOOK FOR A MATCH. >> APPROXIMATELY 60% OF THE TIME. >> Reporter: DETAILS THAT HAVE HELPED THE LAB IDENTIFY TERRORISTS FROM AROUND THE WORLD. BUT BUDGET CUTS ARE ON THE HORIZON.
