Dr. Lori Turnbull is an associate professor of political science at Dalhousie University and the director of the School of Public Administration. She also spends a great deal of time in Ottawa where she lectures remotely. And she's being very clear about what she's been seeing since the trucks rolled in a few weeks ago. This is not a protest -- it's an occupation. And with the announcement that Justin Trudeau is enacting the Emergency Act has some people accusing the government of going too far. Dr. Turnbull says this is the first time this legislation has been used and there are legislative checks and balances in place. And sometimes extraordinary situations call for extraordinary measures.
