For those of you that took my concerns seriously thank you for your input.

This guy lives 600 miles from me but due to the nature of your business I see him more than normal.

reddeacon has no judgmental aspect it is simply a name from a 70's comedy show and is loosely reconstructed from dead recon.

I came to a pilot site because initially I was concerned about the potential of him going off in the cockpit and endangering hundreds of lives. I agree that of equal concern would be his on the ground behavior as well.

I also appreciate the advice on the consequences of contacting the airline directly. I don't want to impede his livelihood but I don't want him risking others as well.

Again, thanks for the conscientious replies. As suggested I will let his peers determine if he is a danger to his profession.
