Here's a great scientific investigation

Evidently Michael Mann, fabricator of the infamous hockey stick graph, has been exonerated of the fourth and final charge of academic dishonesty by a group of his peers. What did the investigation consist of?

Glad you asked. According to the Fox article:

So the panel asked Mann five questions, spoke with his boss, and interviewed three other climate scientists. Case closed.

Translation:

Well, we asked him and his buddies a few questions, and they all said he was innocent!

They're going to have to do a little bit more thorough work than this to make me believe they're actually doing due diligence.
