My sister is a lawyer and has been watching this trial. She also teaches a litigation class at a large law school, so she knows a thing or two about trial law. She thinks the prosescution is deliberately trying to get a mistrial because they don't really want him to be convicted. Can't be convicted if it never goes to the jury. She said they are doing things that any lawyer knows are not allowed. So much so, that she thinks there's no way it can't be deliberate. in here words, no one who passed the bar can be that incompetent. If it ends in a mistrial, there's no conviction and no riots / protests as a result of a not guilty verdict. So a win/win for them in their eyes.
