5 Things Canadians Learned About The Parliament Hill Attack

OTTAWA - RCMP Commissioner Bob Paulson went before a Commons committee on Friday to release a cellphone video made by Parliament Hill shooter Michael Zehaf Bibeau last October. Here are five things learned from Paulson's appearance:

— The Mounties have not figured out where Zehaf Bibeau obtained the lever-action rifle he used in his attacks. They released a photo of the weapon — complete with a broken forestock — on Friday. Paulson said the rifle "seems unique" and he hopes someone can identify it.

— A toxicology screen performed as part of the autopsy found neither drugs nor alcohol in Zehaf Bibeau's system.

— Zehaf Bibeau's behaviour changed in the months before his attack, to the point where Paulson said some of the people close to him ought to have noticed and warned the authorities.

— Zehaf Bibeau took a guided tour of Centre Block of the Parliament Buildings in the days before he died in the main hallway. Paulson said there was nothing in his appearance on the tour that might have piqued the interest of security.

— Paulson blamed the entire "jihadist movement" for attracting and developing individuals such as Zehaf Bibeau.
