"Two young people on the same page. A young Bill Clinton and a young Alan Dershowitz," he explained when we met in his New York City office.
He's one of the biggest legal minds in America. We went to the Big Apple to talk him specifically about Michigan's longest serving non-violent juvenile offender, "White Boy" Rick Wershe. Dershowitz has examined the court pleadings and says it doesn't add up.
"When I read the record on this case, I said to myself, 'There is something I don't know here.' There is something that is being kept from me, some information that the government has on this guy that they're not telling us, and in a democracy you can't have secret files. Everything has to be out in the open," he said.
Dershowitz can't see any reason Wershe should still be behind bars.
"This is a terrible, terrible injustice," he said.
Wershe was 17 when he was convicted of selling cocaine, but has no record of violence. Dershowitz said Michigan is treating him worse than killers.
"The idea that he is being kept in jail because of something they know but won't share with the general public is completely antagonist to American democratic principles," said Dershowitz.
Wershe was one of the best police informants of all time in Michigan. He helped federal officials put dozens of bad guys away, including dirty cops and former mayor Coleman Young's brother-in-law and niece. Wershe was promised his cooperation would earn him favor for release. But he was double-crossed, he said, and remains behind bars.
