A “right-wing extremist”? Maybe. But maybe not. The Islamic State issued this call in September 2014:
So O muwahhid, do not let this battle pass you by wherever you may be. You must strike the soldiers, patrons, and troops of the tawaghit. Strike their police, security, and intelligence members, as well as their treacherous agents. Destroy their beds. Embitter their lives for them and busy them with themselves. If you can kill a disbelieving American or European — especially the spiteful and filthy French — or an Australian, or a Canadian, or any other disbeliever from the disbelievers waging war, including the citizens of the countries that entered into a coalition against the Islamic State, then rely upon Allah, and kill him in any manner or way however it may be….If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman, or any of their allies. Smash his head with a rock, or slaughter him with a knife, or run him over with your car, or throw him down from a high place, or choke him, or poison him….
“Man with knife stopped as he tried to attack Ceremonial Guard on Parliament Hill,” by David Pugliese, Ottawa Citizen, July 23, 2018 (thanks to Graham):
Ottawa police are investigating after a man tried to stab a member of the Ceremonial Guard on Parliament Hill Monday.
Department of National Defence official Daniel Le Bouthillier said the incident took place Monday at 10:15 a.m. on the lawn of Parliament Hill, during the Changing of the Guard parade.
The man was armed with a knife and attempted to stab a guard member. “Due to the quick reaction of our soldiers, RCMP and Parliamentary Protective Services, the potential threat was identified and neutralized,” Le Bouthillier said. “No one was injured during this incident.”
The man was arrested.
As the matter is under investigation by the police, any other comments at this point would be inappropriate, Le Bouthillier said….
