No intention to suggest that you are anti pilot or aviation.Your contributions are thought provoking.
I guess the summmary of this thread might be that there a mutiple risk factors affecting pilot performance and that in the scheme of things the powers that be have focussed on one, namely alcohol (using Stasi like security methods and draconian legislation) to the almost complete exclusion of other factors that may be just as important, or more so, thereby adding no additional value to safety.
