I was in Kenya last month and flew through AMS, and several co-conference participants were astonished and appalled at the thoroughness of the pat-down searches at Schiphol.

OTOH, they paid no attention at all to my empty water bottle.

In Nairobi, they scan your suitcase and bags as you enter the airport and, as far as I can tell, pay absolutely no attention to any amount of bottled liquids at any time.
