This is an article focusing on Canada and how it may be unprepared for a terrorist attack. Back when she was a law student at the University of London in the mid-seventies, Anne McLellan's local Tube stop was Russell Square. It was in the tunnel between that station and King's Cross that one of the London subway trains exploded last week, killing at least 21 people and wounding many more. When McLellan, Canada's minister of public safety and emergency preparedness, saw the TV images of her old haunts now serving as backdrops for interviews with witnesses to carnage, her thoughts flew back. Many more Canadians have studied or worked in London, or simply taken a vacation there. But if there could be no questioning the personal intensity of McLellan's reaction to the latest terrorist outrage, some experts were questioning the adequacy of the federal anti-terrorism strategy she oversees. Since 2001, the Liberals increased security spending by more than $9 billion, on everything from hiring more intelligence agents to revamping airport procedures. But critics who have kept close watch since then, most prominently Senator Colin Kenny, the Liberal chairman of the Senate standing committee on national security and defence, say the money is inadequate and a sense of urgency is missing. Following the nightmare scenes in the British capital, Kenny is hoping a surge in public pressure will force the federal government to get more serious. Any look at federal security policy needs to start by asking whether enough is being done to boost Canada's ability to stop terrorists before they strike.
