Agreed with most that it was clever and well-done, and just the right show to do this kind of an episode if anyone was going to.
Yeah, I was wondering both of those things. Wouldn't it be possible for the defendant and his attorney to have a private line of communication (separate devices where they could exchange texts or just talk when they're both muted on the group chat)? And I haven't been using any of the various software in real life, but I'm surprised there's not a feature to appoint a moderator (Lola in this case, of course) who can designate one person to talk at a time, with the lawyers perhaps having a pre-arranged hand-signal for when they want to object. Defendants and witnesses piping up mid-arguments wouldn't have been put up with during a live trial, presumably, the judge would be yelling at counsel to muzzle them.
Honestly, I wouldn't mind seeing this plotline extend for a few episodes into the next season, just to explore the logistics and ramifications of it all. Obviously we all hope that restrictions can be safely lifted someday soon, but there were very fair points made here about perfect being the enemy of good, and in a hypothetical situation where in-person trials can't be resumed in a timespan where it would be remotely ethical to the people involved to continue delaying them, some alternative would need to be found. It would be much more interesting to watch that scenario play out here than in our world with real lives at stake.
