Hennessey is a wimp for not naming and shaming. Points for calling out BS, but still a failing score for him for failing to do anything constructive.
The WSJ still has some heft. He should have gotten off his butt, scheduled an interview with a senior official with some generic language of his own, and then handed it to the official, reading it aloud while recording, and demanding he explain it in plain English.
And ask the Secretary of Health to comment on it as billing fraud.
You're right... more needs to be done. But at least the guy's making a real effort about being a journalist. There is hope.
