david. there has been this video that they had to apologize about the homeless man came out. there's also been other revel lags revelations, are we going to keep hearing more dribs and drabs like this and one could be explosive? or do you think we basically know the evidence that they have at this point? >> well, we do have something coming tip end of this week. a hearing to determine whether or not expert testimony will be allowed from the prosecution regarding those 911 calls. what they were able to hear in the background. so that's going to be significant. that's going to be a fairly big fight. if that is allowed in as evidence, then the defense is going to say well we're going to need more time to come up with our own experts and possibly delay the trial some more. every point is going to be contentious. you know that everything is so polarizing about this case. it's going to be argued all the way to the bitter end. >> thank you very much, david mattingly. you're going to be covering that trial for us "outfront." still to come, a 10-year-old
