That was an impressively stupid and/or lazy fuck up, to a point where I think Jones could have a lawsuit against his attorneys there.
IANAL but it does seems like "sending an entire copy of your clients phone and making no effort to redact it" could be a thing that, you know, is bad counsel.
No, the lawyers can argue about the scope of what they show the jury during trial. There are plenty of rules against biasing or inflaming the jury with unrelated material.
