All true, yet none of it relevant here.
We don't know the facts, nor will of us ever serve on a jury on this case (civil or criminal), nor are any of us ever likely to serve on any jury on a case involving a bicycle v. motor vehicle collision with injury or death. (because we'd be disqualified through voir dire)
So, if we're interested in change, we might direct our attention to those things that we can control and/or change. namely our own actions, and those whom we might influence.
This isn't to say, we shouldn't try to improve things in the big picture, just that we should talk to those who are listening, and in a position to do something.
