Just remember Trident G-ARPI. Stress before flight caused the Captain to have a heart attack, after aggravating a previously unknown heart condition. 116 died.
Try as we might to not rise to the Security bait, sooner or later some new humiliation will be sprung upon someone who will argue. Assuming the arrest/breathalyser/DNA-taking/charges dropped is over quickly, the pilot will end up at the controls in a stressed state. No doubt rsruggit and friends will deny all responsibility for any ensuing disaster.
