To be fair to the security people it could have been a genuine error. If they thought they smelt alcohol then perhaps they were correct to report it. Note the words could and perhaps.
On the other points, I for one as an aviation professional am happy he has been proven not to be operating under the influence of alcohol - something I doubted from the first.
I wonder how many of the "string him up" club will come forward and apologise, maybe they might start a separate thread on here!
