Er, Jack The Lad, I don't think you understand what TR4A is trying to say! He's highlighting the major points of the newspaper article, the link to which he's posted, maybe for people who can't be bothered to read it...!
He's not saying that T.S.A. guys apprehending flight crew who are over the legal limit before a flight are, in any way, better or worse than searching for terrorists themselves or, indeed, terrorism in general. He's just reporting from the article, (which, possibly, he should have directly sourced and quoted from above his comments, although I don't know the full protocol!) that some pilots and T.S.A. screeners don't feel that it's the T.S.A.s responsibility to screen for pilots under the influence of anything. I'm not even going to comment where the T.S.A.s job description begins or ends, I'm just defending TR4A's post, which, in my humble and not so important opinion, you attacked unfairly.
M.G.T.
