The Harper government is being urged to reflect calmly on the Parliament Hill shootings before changing the laws.

National security expert Wesley Wark, who teaches at the University of Ottawa, says the key question is:  Have the security laws passed after 9-11 served Canada well?

Wark adds only once that’s been answered should the government consider changing resources, organizations or laws.

Otherwise he claims officials would merely be flailing in panic, something he’d like to think is un-Canadian.

The government was already set to introduce changes to the law governing Canada’s spy service before yesterday’s shootings.

Prime Minister Stephen Harper told the Commons today, the proposed amendments would be ”expedited” and give the Canadian Security Intelligence Service more power to track terror suspects abroad and provide blanket identity protection for CSIS’s human sources.
