The judge may have gotten sick of Muhammed "representing" himself--with the lawyers feeding him questions and telling him what to object to.
I always heard that once you decide to represent yourself & the trail begins you CAN'T then say "oh, sorry. I have changed my mind". It's kind of like when ya choose a trial by jury, then part way through you feel it's not going your way, so you then call for a trial by Judge.
Any Lawyers out there care to shed some light on this?
