Life Inside The Real "CSI"

Dusting for fingerprints
Sept. 11, 2001, saw the deadliest terror attack in history. But the carnage that filled the streets of lower Manhattan was also the largest and most complex crime scene ever to confront the FBI, CBS News correspondent Bob Orr.

"On that day, a lot of people just ran downtown like everybody else and were trying to collect anything that appeared to be an item of evidence," said Elizabeth Rosato, coordinator of the FBI Evidence Response Team.

Rosato was among those racing to preserve that evidence. She's head of New York's Evidence Response Team, the FBI's real-life version of "CSI."

On television, forensic investigators juggle multiple crime scenes and neatly wrap up cases before the last commercial break. But in reality, it can take eight hours for an FBI evidence team to take photos, dust for fingerprints and collect evidence from just one car.

"It's great to see it solved in an hour or half an hour, and I like watching that too, but for the most part, it is very, very slow methodical work," Rosato said.

Orr asked: This is basic police work, at grass roots, trying to get the kinds of clues that will help you solve the crime?

"Absolutely, the nuts and bolts of how a case gets solved," she said.

A case, for example, like the terrorist bombing of the USS Cole. FBI evidence experts scraped explosive residue off the belt buckles of surviving sailors, allowing investigators to link the blast to al Qaeda bomb-makers.

That was a victory in what has become the FBI's primary mission — counter-terrorism.

Unlike bank robberies and street crimes, terror cases often require evidence collectors to worry less about making a case and more about stopping the next attack.

"You have to look at the circumstances and what is your ultimate goal. Is it a prosecution, or are we racing against the clock to prevent another disaster?" Rosato said.

It's a lot of pressure on the 40 FBI agents who make up Rosato's team. While it's not quite like television ...

"Sometimes, I wish it would be that glamorous," Rosato said.

... their work is critical. And the stakes have never been higher.
