How much does it cost to prosecute a hundred radical people with no solutions, just lots of anger towards those that don't share the wealth with the protestors and us. If our wealth was distributed equitably, those radical anti growth and anti export fools might not be so angry. The problem is too much tax, not enough freedom and opportunity  created that angry crowd left to fend for themselves in dead end jobs because of neo liberalism left the angry anti-pipeline folks with little other than the short end of the stick. Mulroney sold out our manufacturing sector and burdened us with GST.  The answer is simple, American oil has been against Canadian pipelines and funds groups like those protesting in Ottawa. It has nothing to do with not enough carbon tax. Protestors should be protesting the GST, the real problem facing ordinary folks. If the GST is so great, why doesn't the USA have one? Because it is grossly unfair. After tax income is ours, not theirs to poach. GST kills jobs here.
