Well, AOG, you've seen one counsel's opinion, with which I agree. Do you get the point about not kowtowing now? Or do you feel that allowing these men to be called by some preferred Muslim name is kowtowing but allowing someone who wants to use a non-Muslim name to do so is not? Or is your objection that they are defendants to serious charges and should be denied a right acknowledged in law for others?
As to not guilty, they are entitled to put the prosecution to proof, but they may be running insanity or duress, for example. Out of interest, it sometimes happens that defendants insist that they want to plead guilty when they are not; I have had this happen, and it took all my powers of persuasion to get the client to have not guilty entered. And I have seen someone plead guilty when they shouldn't have; the barrister defending didn't ask me, prosecuting,whether I had my witnesses ready. I hadn't and had no real prospect of their attending or being found. She offered a plea of guilty to a slightly lesser offence , which I accepted. Just goes to show; you need experienced counsel if you are guilty ! Had she asked, I'd have had to answer truthfully.
