ALBANY--The FBI knew what the Boston bombing suspects looked like long before they asked the public to help them determine who they were. A digital detail as small as matching remnants from the backpack that housed the bomb to a person in the crowd carrying that same brand of bag is crucial.
"The average person looks at visual data quite differently than law enforcement. There is not a case that goes by that we can't glean something from that case no matter how poor the visual data is," explains James Kennedy, the manager of forensic video analysis for the New York State Police.
According to Kennedy, there is rarely a smoking gun in a digital manhunt. Clues are sometimes garnered miles and hours from the actual crime.
