Comment: Aside from the embarrassment Kenoi's "partying' brings to himself and his county, drinking to the point of incapacity is selfish and irresponsible. 

What if there had been an earthquake, tsunami or other disaster on the Big Island while Kenoi was in a drunken stupor?

Being a mayor or other official is not a licence to do whatever you feel like doing. It comes with authority and a burden of responsibility for public welfare and safety.  Clearly, Billy has lost sight of this.
