Many of the talking heads on cable are stating that the witnesses so far have been very emotional and have given compelling testimony- One of the attorney commenters described being somewhat upset with the line of questioning by the defense, attempting to portray the crowd as "unruly" and hostile.
What I have learned from watching trials and listening to talking heads, is that what they think may be the total opposite from what the jury is thinking. We Simply don't know how the testimony from these witnesses is impacting them. I know this though, when a defense attorney can rile up a witness to a point where a judge has to admonish that witness, it is not a good thing for the prosecution.
I find the defense's relentless questioning of these witnesses troublesome- With their questions, they are planting the idea in the minds of the jurors that this crowd was so out of control that the police were unable to concentrate on the man they had in custody. While I find that theory ludicrous, it just might work. I've seen stranger theories in trials that I never thought would be successful, but in fact were successful.
