Right. He was just a drug-crazed jerk who just happened to be a convert to islam.
And according to one of the members of Parliament, who was on his way to their weekly party caucus meeting, he drove a beater car that is stopped right in the middle of the road with the hood up.
He shot one of the guards in the leg at the side entrance, which did not have a metal detector. A reporter who is sheltering in place, was told by a guard, he was also most likely wearing body armour, because there was a lot of gunfire as he went down the long hall to the library.
Body armour is expensive. The car though old, had no plates. How gave him the money for the weapon (kind of quaint looking) and the bullet-proof vest.
Although, many Canadians know of the side entrance with loose security for people with passes, would a former drug addict have it together enough, to see that as a soft-spot to make his bloody ingress?
