Makes me wonder that Philip Testa may have been whacked because he had a mustache.

And what about Frank Cali?
In the last decades you see mobsters growing a mustache more often, so I'm wondering how much this rule still applies. It seems that it's more a code of conduct or behaviour and that higher ranking mobsters can pretty much do what they like.
