Do y'all remember another trial in which a defense witness testified during direct, but the cross exam was delayed while another defense witness testified? I can't remember that happening. It's also inconceivable to me that JA could have testified in secret, and there might never be a cross exam. It's like a bad sci-fi movie where the only real human in the courtroom is the prosecutor.
I was puzzled about this at first as well , but I think the explanation is that the hearing first thing this morning was, for some reason, going to be about the computer porn, ie, the trial within the trial, which is separate from the main trial, and therefore has a different set of witnesses. So the actual flow of the main trial is not being derailed, it's just that the entire main trial is being derailed in order to deal with the trial within the trial. It's simple within its complexity.
