It is the first terrorist incident in Canada committed by a refugee. He arrived a few years ago, when the refugee screening process was still rigorous. In the last two years we have admitted so many more migrants in such a hurry that the vetting process could not have been complete, despite all assurances. We should expect more terrorism from those whom we have failed to investigate thoroughly, since clearly they have the propensity to be radicalized and turn into terrorists, as this attack shows. The Liberal government have put us in a precarious situation, jeopardized our peace and security. To make matters worse, we continue to admit illegal migrants through unofficial crossings. They get to live among us until their cases are reviewed and their endless appeals are exhausted without a thorough  investigation about their character, background, affiliations etc.. Impossible to know how many are a potential security threat.  JT is going to wear the next terrorist act by a migrant!
