I'm reading your other comments in this thread, if you are asking these questions in good faith then I'll respond in kind.

Mr D.O doesn't get overly emotional in his videos, in fact he approaches serious topics with a lack of emotion to deconstruct the factual accounting of the incident step by step.

His personal agenda? You mean how he's as ready to call a bad cop a bad cop as he is to explain why an incident was justified from the perspective of the law & officers?

That's not a personal agenda, that's being rational.

Those videos you're referring to, which one's? 95% that are coming out from the protests are edited down in order to go viral with the narrative. D.O tends to wait until... and this is horrific I know... there are enough facts, statements & footage to give the full picture.

However, as others have said, the first thing to keep in mind is he is a content creator. It's a platform which only a portion of it consists of police deconstruction videos, you may be asking too much from someone who has never stated that was their mission.

Maybe... and I mean this with sincerity, do it yourself?
If you genuinely feel there are that many videos that need to be stripped down and taken apart publicly for an audience to watch, what better way to send the message you want to see than doing it yourself?
