In an article on '' The Daily Beast '' website , Jacob Siegel equated both Couture-Rouleau and Zehaf-Bibeau , " the killers who brought terror to Canada this week " , with the 2014 New York City hatchet attacker , saying " like the killers who brought terror to Canada this week , the New York attacker is being called a " lone wolf " , meaning he acted essentially on his own , Couture-Rouleau and Zehab-Bibeau seem custom made for the stray dog profile , and the kind of terrorist the West could be seeing a lot more of in the future " . He cites a paper by Brian Michael Jenkins of the RAND Corporation . Jenkins described them as " stray dogs , " rather than lone wolves , characterizing them as " misfits " who are " who are moved from seething anger to spontaneous deadly action " by exposure to Islamist propaganda
