As part of her sentence for conspiracy and arson, imprisoned B.C. environmental activist Rebecca Rubin has been given some reading homework.

U.S. District Court judge Ann Aiken ordered Rubin to read Malcolm Gladwell’s book, David and Goliath: Underdogs, Misfits, and the Art of Battling Giants, along with Nature’s Trust by University of Oregon environmental law professor Mary C. Wood. According to the CBC, Aiken suggested Gladwell’s book could teach Rubin “non-violent means to protesting systems she perceives as unjust.”

In late 2012, after seven years of living as a fugitive in Canada, Rubin turned herself in to the FBI for participating in 20 fires set by the Earth Liberation Front and the Animal Liberation Front. She was sentenced to five years in prison, 200 hours of community service, and ordered to pay nearly $14 million in restitution.
