The entire trial was televised and the facts are well documented through many good videos. There were also a number of lawyers who were directly involved in the case who live streamed through the entire trial as well and there was a ton of inside info as well as top level experts discussing how the facts played out. Rekietalaw was just one lawyer who started out streaming the pretrial motions and it snowballed into the most watched live stream and coverage of the trial.
So it is fair to say that all information wasn't publicly available it is safe to say almost all was and so much more beyond what the jury knew.
I’m not as certain about that as you are, even with all the televised parts of the trial and the streaming.
I’ve unfortunately had to sit through five murder 1 trials for the two men who heinously beat my brother to death.
I got to see so much that the general public is oblivious to, it is NOT like the show Law & Order. It’s considerably more complex.
The judge will always require the jury to leave the courtroom when new evidence or other issues are being argued over for their relevance and other issues that may influence the jury but not be legal to become admissible. The jury will also be asked to leave for numerous other reasons, like outbursts by family/friends or anybody (including the lawyers) disrupting testimony.
I’m sure the judge had the power to shut down televised portions for evidentiary arguments that might end up getting back to the jury.
Nevertheless, I certainly don’t know most of the evidence and therefore can’t judge. However from the modest amount I did see and watch, it appears like his intention was to help people and knew he had to be armed to do so. He feared for his own life as he was being attacked while trying to run away - that meets the requirements for use of lethal force in self defense in Arizona and most states (I can’t speak for Wisconsin though).
