In case you missed it, here is David Bianculli's review of 'The Central Park 5':
The case, by now, is anything but a whodunit; the actual rapist and attacker eventually stepped forward and confessed, and DNA samples from the crime scene proved a perfect match. But that didn’t happen until five teenage boys had been convicted of the crime and spent seven years in prison. They claim to have been coerced into giving false confessions, and the documentary makes a compelling case on their behalf.
