His lawyers were objectively bad. You'd bring in a new team and fire them also.
Example: they sent a copy of his cell phone to the prosecuting attorney on accident and didn't request it back in time, so 2 years of his text messages were used against him.
That was literally the last lawyer he had which ran the trial (Reynolds).
And the reason his lawyers were so objectively bad was because they all had about 1 month working on the case before getting fired and replaced by a new lawyer.
Meanwhile, the plaintiffs had exactly 1 set of lawyers representing them (1 in TX and one in CT).
I'm not joking when I say that Jones went through about 20 different sets of lawyers throughout the cases. You can listen to his various depositions and there's not a repeat defense lawyer in any one of the depos. I highly doubt they were all just uniquely terrible, especially given how much money Jones has. A few were really terrible (Norm, Barnes). Reynolds was actually one of Jones's better lawyers, he just messed up. Unsurprising given how little time he was on the case.
IIRC, the reason for the phone copy getting shared was because of the case hand-off between reynolds and the previous lawyers. The TX lawyers were CCed when they shouldn't have been. And in the process of getting ready for trial, reynolds missed the email informing him of the mistake.
