As much as I'd love to see anything blamed, directly or indirectly, on TSA, the passenger in question appears to have been headed TO the U.S. This incident was simply the failure of Canadian airport security to detect an item that is banned in Canada. However, this raises another very interesting question: What happens when flights from the U.S. empty into international terminals at foreign airports (e.g. AMS, CDG, SYD), and those countries don't permit knives? Australia, for example, is especially picky about "stickies" in hand luggage -- even prescription meds with hypodermic needles are only allowed by prior arrangement with your airline. Are small knives permitted in the EU? AMS would be a much less friendly airport if all passengers from the U.S. where shunted directly to customs & security. CDG is never particularly friendly anyway ... Latinos Post: TSA Rule Change May Have Inadvertently Shut Down Toronto's International Terminal Toronto's Pearson airport grounded international flights early Saturday morning, after a pocket knife was discovered in a passenger's carry-on luggage. The passenger was likely on his way to the U.S., where the Transportation Security Administration has recently authorized rules that say passengers are allowed to bring such items on the plane in their carry-on bags.
