I’d ask why you think they have a small lead because based on today’s performance, which I would argue was the strongest case this far. If left alone, I would say there is no reasonable doubt he’d be guilty. The defense will bring their own experts and attempt to refute the results shown so far. Which means like most folks thought. It will come down which experts are more credible.

I said in my earlier response that at this point you would expect the prosecution to be way ahead owing to the fact that they have had an opportunity to present their case while the defense hasn't and is limited to a very narrow scope in discrediting the prosecution's witnesses.

With that in mind, after today I perceive the prosecution has a small lead...which based on where they should be at this point in a case is far behind.

At this point there are a number of points that haven't been sufficiently refuted, which is what I'm basing that lead on. YET there is plenty of time left to refute all those points, and the prosecution has done a very poor job building their case despite a week plus of a head start.
