Last week, in DUB, the screeners wanted to see my Logbook. I asked if they were CAA inspectors, to which I got a negative reply. I thus refused.
They subsequently didn't want to let me through, after which I told them to write-down the reason not to allow me to my aircraft and send it to the CAA and my airline. I also told them to show in writing on which rule they based their request to oblige me to show my logbook. They then immediately let me through. Pathetic.
DO NOT ALLOW ANY CRAP FROM SECURITY.
