I don't think he's innocent, but I think there were others much higher-up than he was that were aware of this and actively contributed in the fraud.

Also, didn't VW do this in Europe, too? Are we to believe this guy in the U.S. is responsible for the emissions cheating in Europe, too? At the very least top EU execs would've been aware of it, even if he was the creator and the evangelist for the device.

As far as the U.S. federal government goes, I doubt we'll see anyone else charged. They've already settled with VW, and this guy taking the fall was likely part of the settlement. We may still see some states continue their cases against VW, but I wouldn't be surprised if the DoJ pressures them to drop their cases.
