What exactly do you want people who smell alcohol on a pilots breath to do? Ignore it because they are flight deck crew? The accusation is easily made, and sometimes made for non too pure motives... However its easy to refute, just one continuous breath of between 10 and 30 seconds into an approved machine, game over...if no drink has been consumed no harm done... if he has been drinking ... Well only one person to take the blame. I really can't see why you are blaming the guy from security?????
