don’t need any such “proof”

I'm gonna stop you there. I'm okay with no benefit of the doubt in terms of them being bad actors, but your worldview still has to be built at the bones and joints out of things known to be true otherwise there's no stopping you from believing every conspiracy with no guard rails.

I don't think there's yet a specific smoking gun on this front, but I think once there is, then it is okay to presume it likely happening in other instances. But no smoking gun just yet.
