There's only one thing Cook County prosecutors hate more than crime, and that's being proven wrong. This leads us to journalism professor David Protess and his class. Already having helped prove the innocence of 11 men behind bars, his investigative journalist students have spent 3 years investigating the case of a man convicted of killing a security guard. The students believe they have evidence that shows the wrong man is in prison. In response, the Prosecutors Office has issued subpoenas to professor David Protess seeking his students’ grades, his syllabus and their private e-mails. They claim since the team was made up of students, they may have been under pressure to prove the case to get a good grade. “Why are we talking about our grades when we should be talking about whether there’s an innocent man in prison?” said Evan Benn, a former Protess student mentioned in the state’s subpoena.
