i find myself on the other side of this issue.
i am born in BC my wife is an immigrant so with two perspectives we come out the saying the same things. i watched the same video as everyone else and i don't see what everyone else expresses, i see one man destructive, belligerent, uncommunicative, and uncooperative with people and police this man emigrated to Canada and by some media reports had up to seven years to learn the most basic words of need before coming to this country, he had a duty to do so.
you do not destroy items in an international airport no matter your personal level of frustration and when confronted by the local police you do not ignore them and you do not move behind a table of items and arm yourself.
the out come of this incident is in short a tragedy like any truly important tragedy the central character is the start and conclusion.
