Even though security officers did a "brilliant job" of responding to last month's attack on Parliament Hill, Canada's national security infrastructure is fragmented and needs to be updated, according to a former commander of Canada's special forces.

Retired lieutenant-colonel Steve Day, a former leader of the elite JTF2 counterterrorism unit, was asked by the CBC to undertake a frame-by-frame review of CBC News and security video footage captured during the Oct. 22 attack on Parliament Hill by Michael Zehaf-Bibeau.

Day found "systemic" flaws but concluded that the officers on the scene, despite a lack of specialized training, acted properly in containing the threat.

Zehaf-Bibeau died in a hail of gunfire outside the Parliamentary Library after first shooting Cpl. Nathan Cirillo at the National War Memorial, then wounding a security guard at the entrance to the Centre Block on Parliament Hill.
