Don't report it - ever, especially not in the U.S..
Sorry to be Kafkaesque about this but given that both airline and government security staff are not very bright, there is every chance that at least one of about three things happening:
Your good intentions will result in your being labelled a "trouble maker" and get you earmarked for special security screening whenever you fly.
You are accused of actually being in league with terrorists for collecting and analysing information on security procedures. You now make the "No fly" list.
You are abused in public for having the temerity to question the authorities.
I could go on about the breaches I've seen even on my infrequent trips. In addition, the latest photgraphic "flight crew Identification" issued to me as a student pilot is no different to that issued to the holder of an ATPL licence - that has GOT to be a mistake!
Just act like a good sheep. Go with the flow, and never, ever mention terrorism or hijacking withing five miles of an airport.
