Let me just point out something that has been overlooked in my company. When you report a colleague to the C.P., allways give the person you're reporting a heads up on what you are doing. Allways be honest and up front about it, even if they might mouth of about it, that way you have cleared your back and it gives the person a chance to answer your critique. Allways take discussions like this behind closed doors and don't involve others unless it is to confirm your feelings.
I find this obvious, but apparantly a few of my colleagues don't and therefore I thought I'd just say it as nobody else has said it. It creates a much more secure atmosphere amongst colleagues and it helps contain unnesecary rumours.
