There was concern of over-reach when Pierre invoke the War Measures Act also. The War Measures Act included all of Canada, not just the geography the FLQ was operating in. I was fairly young at the time but I still have a recollection of the bombing, kidnapping and murder. I can't reconcile the current protest demands with say the FLQ manifesto[0]
