Just to be clear, I do not know the PF, nor the circumstances surrounding the alledged CM.
However, if the PF fessed up straight away about the camera then we wouldn't be at CM stage would we, Isn't the CM to do with the fact that he didn't tell the truth straight away, as opposed to the incident itself? If he lied about what happened then IMHO it is entirely correct for him to face disciplinary action.
