What manipulations would those be Cassandra, inviting respected experts to speak to the special parliamentary committee? How manipulative to introduce evidence and expertise into the process. 

Perhaps Nathan Cullen, like many Canadians,  was deluded to believe Justin Trudeau and the Liberals might actually want evidence based policy. Like many others, he learned that that too is just another Liberal lie.

 Justin Trudeau made his promise with no conditions, qualifications or caveats....repeatedly.  Then he didn't even have the courage to face the media or Canadian public to break his promise. He sent a 29 year old rookie to do it for him.
