I have read all of both (perhaps you missed one?) of SAS's posts - indeed now for a second time at your behest SLF.
I understand (and have personal reason to do so) his anger and the harm that was done to himself/family/friends by a drunk driver.
I will still not support the premise that the individual concerned should "never, ever flys [sic] again".
If under reasonable professional measurement he is treated and cured (and one contributor who, apparently knows the individual concerned, suggests it was a 'one off aberration' along the lines of SAS's self admitted "reporting whilst not feeling 100%" rather than a deeply infiltrated problem) for a medically recognised condition it is my opinion that he should then -and only then - be able to continue to enjoy the priviliges of his licence in the same way that Chuck, a couple of colleagues who I have known and a larger number of their fellow professionals have done.
