So he leaves one crime show due to 'too much violence on tv' if I remember right, and joins onto another? If he was signing onto a humor show, or something educational, or WHATEVER it wouldn't be so strange, but from the summary it sounds like another drama.

That said, there's a lot of potential if he would come back to CM for an episode or two, especially if he came back as an unsub. That'd be sweet. However, I'm not at all expecting anything like that to happen.
