What we can be pretty sure of is that someone - either the California Highway Patrol, the local Sheriff's Department, or the District Attorney -are lying about things like the severity of the collision, availability of video, witnesses, witness statements, etc.
There's a good chance that all three authorities are lying to some degree, trying to cover for the husband of the House Speaker.
And most of the media are complicit - just like they were with the Hunter Biden laptop story, the Steel dossier, etc. etc.
