If the TSA said something at the security check point, he would say he is sick and non-reving home. No crime commited
Exactly.No one should be flying if under the influence, that goes without saying. But if you can stop someone before they commit a crime, why not do it. Why wait until they are in the process of a crime, when saying something at screening would have the same effect, keeping them off the flight. Same as if your Captain showed up drunk in the hotel lobby. Would you tell them then that you thought they were drunk, or wait until in the cockpit and then call the cops on them.
