I was surprised that just recently on an in-state flight from Spokane to Sea-tac and back, I did not get scanned at all, I only got the metal detector treatment. I had thought that the gawk-at-you-naked scanners were the default everywhere no matter where you were traveling. I was surprised to find that leaving Tegel in Berlin was easy as can be, short lines, quick trip through the metal detector. The entry process at Sea-Tac was another story though. It took forever. You got grilled, you got the German Shepherd dog sniffing your crotch, and you had to wait for all your bags to be x-rayed. Some of the agents seemed to be behaving in a very rude way, in particular I remember one agent seemingly being a real jerk to some poor old guy who didn't speak English well. I remember thinking how bad an impression of the US that the foreign visitors in line must be forming. I was at that moment embarrassed to be a citizen. [edit: %s/x-ray/metal detector/]
