Teen put in Rikers (NY) for 3 years without ever having been convicted.

No priors, no evidence, no recovered property, a single eyewitness, charges suddenly dismissed 3 years after his arrest with no explanation, and was only offered a plea deal (which he denied) after having been in more than 2 years.  Likely the plea deal was offered when they realized they did not have the case, yet they let him rot for months after that before finally giving up on trying to keep him imprisoned until he "confessed" so the DAs office could tally another conviction and case closed:

Bronx resident Kalief Browder was walking home from a party when he was abruptly arrested by New York City police officers on May 14, 2010. A complete stranger said Browder had robbed him a few weeks earlier and, consequently, changed the 16-year-old's life forever.

Browder was imprisoned for three years before the charges were dropped in June 2013, according to a WABC-TV Eyewitness News investigation.
