Years ago, I fell asleep at FRA, the same day as a small bomb was exploded outside the airport, so there was added security. I was awakened by police who asked me to take my bag and follow them. I was directed to a room with no windows. I was told to take each item out of the bag and hold it up to a tv camera. After I did so, the door opens, and I was told I could go on my way. I was a little nervous, but there were no flight delays, no fear among other travellers, no evacuations, etc. Seems the German police had their act together.
