In another article "what we know so far ......" (No comments allowed) we learn that the perp is a Somali refugee, who was known to police and was investigated for publicizing extremist views, but not arrested. 

Haven't we heard the same narrative repeatedly, like every time there's a mass murder in the US or Europe / England? What is it going to take for the police to recognize that where there's smoke, there's fire? Why do we feel compelled to keep "ignited dynamite" in the country and wait for  it to explode? 

Is it because "a Canadian is a Canadian is a Canadian" (the last one being superfluous and meaningless, but expected from the orator in chief), even when they are not a Canadian, have no intentions of ever becoming or thinking or acting like a Canadian? What obligates us to provide safe haven to those that would see us destroyed? What part of the progressive psyche dictates the need for this dysfunctional "altruistic" behaviour that is thrust upon us?
