In 2007, Hassan Diab was an unassuming sociology lecturer at Carleton University, when he was suddenly told French authorities were investigating him for committing a terrorist act in Paris in 1980.

An external review was ordered into his case, but Diab and his legal team are less than satisfied with its findings.
