By no means do we want Canada to become a police state, to start acting like North Korea or China, which are absolutely deplorable. That said, the objective is to protect ourselves. The world has changed, as have the threats to the world; these darned networks like Facebook are tools for hate-filled propaganda. And it does not necessarily come from here, it may very well come from elsewhere.
Let me go back to the act. Let us suppose that someone posts a video on YouTube in which he suggests attacking Canada or setting off a bomb, but without asking anyone specific to do so. In your opinion, should that individual be charged with counselling an attack?
