I'm just glad that I seem to have passed through whatever set of factors that caused me to be "randomly" selected every time I entered the US for years on end.
Do you usually dress the same, and go through the full body scanners? My wife was upset that she got patted down every time at logan, and then she looked at the display and found out that the TSA didn't like the buttons on the hoodie she liked to fly in. Now she just wears the grey one instead of the red one and flies through every time.
Literally every time I went UK->US 1996 to 2010 I got "randomly" selected by some/all of immigration, security, and customs. I can only assume I looked/behaved dodgy in some way, was on some kind of list, or was just darn unlucky!
Incidents within the EU. Zero.
I've only just got the point where I've stopped scheduling a couple of extra hours of security-slack into my travel schedule ;-)
