Giolla, saying that the security staff at AMS have no specific training is saying that pilots have no training either. The staff ARE trained. They follow a basic course which allows them to man the standard security checks, after which there is on the job training. On top of that, to profile there is an intensive follow up course which is much thougher and longer, followed by more on the job training.
Of course they won't hold a PhD in AVSEC, but neither do pilots know anything really worthwhile about aerodynamics...
Since when do we believe the papers to be correct when they report anything related to aviation? We should know better on PPRuNe! Look, I'm not trying to defend the way things are done in security. I just know it a bit from the inside, and it is not helpful in a discussion like this to say things that are just not true, or worse, quoted from a newspaper.
