Alberta Views Online has a great article by Dave Berry this month -  The Disobedient Albertans; Are Greenpeace's Stunts Outrageous Or Essential?

Civil disobedience on energy issues is rare in Alberta; when it happens it gets media coverage and a strong reaction from government and the oil industry. In this detailed and well-researched article, Dave Berry interviews Dr. Laurie Adkin, a political science professor at the University of Alberta, Mike Hudema, climate and energy campaigner for Greenpeace Alberta and Mario Raynald, executive director of the Pembina Institute and Gil McGowan, president of the Alberta Federation of Labour.
