I’ve been back and forth on this story with half a dozen people.
Each one seems to find a different narrative and “facts” to support it.

I sure as snot ain’t saying LE has all the answers, I for one know that ain’t the truth. But right now, they have the best view of the evidence. Not little audio bites from blocks away, not screen caps from bad cell phone video. But the audio and video from his own gear. The physical evidence from the room and his houses.

Right now, we don’t know what the police know. And until the investigation is complete, we aren’t going to know.
It’s not a superiority thing, it’s an investigative thing.
