Nope.
If Natives were in a PR exercise they would not be protesting in that manner they have. You can certainly say the last 10 years of protests haven't helped improve the public image of Aboriginal people. However, their brand of protest has been highly successful by interrupting the economy. That in turn squeezes us and we squeeze the politicians to do something about it.
Your mention of Caledonia is another myth. No laws were skirted, and no one that committed a crime wasn't charged. In fact there were many charges laid over the protests on both sides, and many of the protesters from both sides received conditional discharges. What most people (and that would include you now you have shown your hand) miss is that our Charter Rights are held higher than domestic law. The duty of the police in protests is to keep the peace, avoid inciting a riot by making rash arrests, and record and catalog the event for future evaluation and charges. That not only happened in Caledonia but at Tyendinaga, Akwesasne and Brantford. At the end of the day justice was properly served and the police act in a reasonable manner.
