It’s a good thing Justin Trudeau acted. Countless nations have been brought down by “mischief.” From sundance at theconservativetreehouse.com:
The need for control is a reaction to fear. What does the government of Prime Minister Justin Trudeau fear so much that he invoked the first ever declaration of the Emergency War Measures Act? A group of middle class Canadians who challenged him. That’s it. That’s the sum total of the Trudeau justification.
Need proof? Well, here’s the lead organizer of the Trucker rebellion, Tamara Lich, who triggered the declaration of a national emergency and invocation of the federal Emergency Act. What heinous crime against the state was she charged with? “Counseling to Commit the Offense of Mischief“.
Think about it.

No, seriously, think about it.
It is true that she may later be charged with removing mattress tags. However, for right now, the biggest domestic terrorist in the history of Canadian politics is currently charged with the same offense as if she stole the lids off the shampoo bottles at the hotel where the Liberal Party of Canada was holding their national convention.
