Your not really offering any arguments to this discussion. If you're interested you can compared the student tuition protests in the US and Canada[0]. Violent or non-voilent, no protest can occur if people don't believe in the right of making your voice heard. In the US you are very good at rationalizing away those rights. I would do that to if I faced the US justice system and frankly that's why I don't spend a lot of time in the US. Plenty of incidents have been written about, from unlawful arrests to free speech zones and jail time for simple Internet attacks.
