Rootbeer barrel defense. Throw them at the wall, see what they stick to.
Ample evidence he's really dumb, but the juries won't be. I hate already for what they'll have to see.
If ever there were a case for the accused to just plead guilty and be done with it, it's this one. He has no defense, he recorded most of the evidence against himself. Diminished capacity in that whiny head, sure, but not so diminished he didn't know right from wrong which is The Gold Standard for competence IMO.
Factory reset alone proves consciousness of guilt.
He needs to plead guilty and go away for good.
