Mayor Kenoi wants off on a technicality

[Chunkster]

The short answer as to why some of Kenoi's underlings were given immunity is that the prosecutors felt it was necessary to get testimony to convict Kenoi. Without immunity, these characters could have invoked their Fifth Amendment right against self-incrimination and refused to testify. In a perfect world these people would be held accountable for any cover up, but in the hideously imperfect arena of the Hawaii criminal justice system, this is the best they can do. And there's a very real possibility that Kenoi could still walk.
