At a New York hacker conference back in July, a German security consultant known only as “Ray” made something of a mockery of one of law enforcement's most important accoutrement: the handcuff. Using plastic handcuff keys that he printed from CAD files on a 3-D fabricator, he wowed the crowd be easily popping open
sets of cuffs designed by multiple European security firms, highlighting the potential for foul play inherent in a technology that makes the sharing of physical objects so simple. Criminals have long made handcuff keys, but doing so required getting one's hands on an actual key and creating a duplicate in a metal shop. With 3-D printing, you just need a digital file--easily shared and duplicated. The capacity to subvert the law is but a mouse click away.
