Francis, my understanding is that when these scanners are implemented, there will be no pat downs (Except for those who refuse to go through the scanners). Scanners are much quicker than the pat downs.
As to kirpan, I don’t think they permit Sikhs to take them on airplanes.
As to your point about terrorist using the allowed items, you have a point there (although the 9/11 terrorists smuggled the box cutters on board). That is why they were experimenting with liquid explosives. Now that liquids are banned, no doubt they will try to find another hole in the security system. It is a never ending game.
Incidentally, why is your ISP displayed in your post? Are you OK with that?
Hello SJP.. Did you watch the clip I attached from CBC many posts back.. It shows how the new scanners will be used and how people will be patted down if an object is detected on them ?
As to Kirpans on Airplanes I doubt they exist since 9/11 but would not put it past anyone. My feeling would be to change any flight I planned if I found out the policy of the airline had recently changed to allow. These policies constantly change with many of us not being advised..
Liquids are no longer banned on Canadian flights as per my last flight out within limitations.. They were still if you went to the US but not within Canada. It always amazed me how they would let women on flights with makeup and all sorts of "liquid" stuff on the name of fashion thru security yet would remove a small container of anti-deodorant.
Terrorist pick not the best but rather the most terrifying targets ( best graphic impact ). It would make much more sense to hit a football stadium then an airplane or even building. But the impact is much more terrifying to have as a thought to be stuck in an airplane at 35,000 or 40,000 feet with no escape then in a football stadium that is wide open in many cases.
And yes they will always remain a step ahead by using conventional items. While security is distracted looking for guns, bombs and such others it is much easier to slip thru with items that no one is looking for. In any planned event such as these, would you want to make 99.9% sure most people have no reason to feel out of place.. This is what scares me the most and why I think this over security is scary. People get a false sense they are protected..
