An interesting question is, given legislative changes since the Trudeau example given... changes made to address a terrorist threat... is it less complex today to suspend Canadian freedoms (for example, hold and interrogate people, limit free speech, military folks doing police work, suspend powers of parliament) in Canada, than in Trudeau's day? Or, is it more complex to do so? And, could it be done for a longer or only a short period? I cannot answer this question. Anyone care to give it a shot?
