How the Secret Service Uses Ink to Solve Crimes (2019)

You may have an image of the Secret Service—suits, sunglasses and earpieces. But, there’s an entire forensics arm of the agency dedicated to solving crimes—sometimes using nothing more than an ink blot. The lab tackles some of the toughest frauds and forgeries, armed with the world’s largest collection of pens, inks and printer cartridges. By comparing prints to a library that includes over 12,000 samples of black ink, this team of experts is able to solve cases from forged checks and counterfeit money to written threats.
