Japan airport security is basically pre-2001 (sans theater)
* keep shoes & jacket on
* metal detector
Unlike:
American airport security
* remove hoodie, jacket, etc.
* slower and more radiative millimeter/backscatter
I went through both Tokyo/Haneda and Chitose airport security this week. Haneda's security was also ok with using a single tray for liquids, devices, laptop, coins etc. for their x-ray machines, in contrast to U.S. airport security requiring separate trays for each laptop, and any liquids or anything else.
I can only conclude that the TSA's extra procedures and expensive radar devices are a waste of time & resources, no more than a perpetuation of a culture of fear since 2001.
I remain hopeful that the TSA will eventually adopt measures similar to Japanese airports and return to just using metal detectors.
