I get the feeling that the reasonator was joking.
I hope.
Yes. That would expensive and to be ethically we'd have to go to an all volunteer jury which would make it even more expensive.
Personally on the jury I would ask for a transcript after every trial and read and reread everything just to make sure I was a good juror and not missing anything that would give me reasonable doubt (even if I already noticed some reasonable doubts those could turn out rebutted so I must be aware of all of them so I don't say "guilty" when there are facts of the case that are cause for reasonable doubt). But most people even people who'd be capable of handling that wouldn't do that. A proper trial requires a thorough combing through all the evidence. There's NOTHING to guarantee the jury does that rather than just go to their hotel room watch TV and eat bon bons until the next trial. And furthermore nothing to guarantee the jury will even pay attention as the trial goes on rather than say, daydream about going to Hawaii or think about the vacation they scheduled for themselves right after jury duty figuring they'd need it after jury duty.
I'm not saying jurors are bad people. Afterall they don't have a choice about being there. But that's even more reason why jurors might not be particularly into playing the role right instead of just "going through the motions and getting it over with". A "go through the motions and get it over with" attitude could compromise the quality of justice in the court rooms. Jurors could have reasonable doubt but give up in deliberations before they really have had their doubts satiated because they want to go home faster. And sometimes that could even just be on a subconscious level for the juror not to realize they really still had reasonable doubt until they are home, and they realize they allowed themselves to be persuaded because they wanted to get out of there so badly.
