Mr. Speaker, my old geostrategy professor told me that a terrorist act is, first, an act of violence or intimidation for political, religious or social ends; second, a structured act; and third, the symbolic act of a perpetrator trying to make his mark. He shared a famous quotation about how terrorism and the media have an incestuous relationship. There was also an element of exclusion in that definition of a terrorist act. Personal motivation was not part of it.
That means that a crazed gunman who climbs a tower and starts shooting people because he is mad that a judge took away custody of his kids is not committing a terrorist act. What he is doing is dangerous and can kill or injure many, but he will be punished under the Criminal Code for premeditated murder.
It seems clear that, when my distinguished colleague defined a terrorist act, he forgot an essential element, which is that terrorism does not include actions that are personally motivated.
