All of that is circumstantial. And none of that can be attributed to Joe directly. That's like blaming Obama for a drone strike that killed 2 hostages when he wasn't even in the loop on any of it. Maybe Joe was directly involved, maybe he wasn't, nobody knows.
And just about every sheriff's department and court system will destroy evidence/exclude it if it doesn't fit some narrative. That is normal practice. He isn't doing anything out of the ordinary. We live in a corrupt system. The fact that it shows more under him is just because their is a magnifying glass on his office. He put a bulls eye on his back, and people are noticing. But again, nothing has happened there that hasn't happened anywhere else.
I'm not saying that makes anything right, but a lot of that stuff just isn't a big deal to me.
