"He does not say he butted him to free himself from this restraint, the taking hold of the arms and the guiding back in. He does not say that he believed it was necessary to butt to get free from that form of arm holding and guiding, be it in fact lawful or unlawful, according to all that we have heard. He does not say that. What he does say, quite simply, is the reason that he butted Mr Blake was to free himself from the very painful finger or wrist lock which he said was being put on him by Mr Blake, and increasingly and becoming excruciatingly more painful. That, he says, is why he did it. That was the trigger for the butt causing, in one way or another, the injury to the face, according to the defendant and in that respect, that sort of lock, none of the nurses, nor Dr Berry, say that such a painful lock like that would have been necessary or legitimate in the circumstances."
