This is TSA mandated procedure. KEF does not re-screen passengers who transit from European (to US) flights; most airports (LHR, FRA, MUC, ZRH, to name a few), do. The alternative is for KEF to re-screen all US-bound passengers just as they do for all US-originating passengers transiting through KEF. I prefer the random screening method to the alternative.
What puzzles me is why passengers are detained (until boarding) after screening--apparently so they don't mix with other passengers in the waiting area but can mix with them on the plane.
