Thanks for posting this. As several of the comments clearly show, most people are clueless to the security risks due to a very unsecure border with Canada. Canada is replete with terrorist cells in almost every major city, especially Toronto and Montreal. The liberal gov't did virtually nothing to tighten immigration post 9/11, a point not missed by AQ.
I posted elsewhere some very real concerns that I have for today's Superbowl because of the proximity to Canada. Hopefully nothing will happen. But there's a reason why the security for it is the largest single security operation in US history!

Perhaps the most dangerous person to every American (no, not Bin Laden, Al Zawahiri, etc...) is Adnan El Shukrijumah. He is thought to be in Canada and has been called the "Mohamed Atta of a nuclear 9/11." He very well may already have a (or several) dirty bombs...perhaps worse. He has been commissioned by Bin Laden to hit the US with a nuclear weapon.

I am equally concerned about the Mexican border and can't believe how poorly Bush has (or better...hasn't)dealt with it. Simply inexcusable. But we must realize that an equal (if not greater) threat exists to the north.
