Sharingan, stuff like the phone calls is just the stuff that we seize upon when defending. It makes a wonderful distraction for the jury, to get them away from what they should be concentrating on, the key and significant evidence. There's nothing new in it, because juries never change. Cicero, who made his name as an advocate, and who wrote a book on advocacy, called this technique "kicking up dust"; the jury lost sight of what they were meant to following. That was in Ancient Rome, and it still applies.
