Justice would never have been served without the video. Remember that. The mother didn’t know what happened. The most the mother could have hoped for was money at that point.

The mother said he was on a routine jogging exercise. This is almost certainly false.
The question remains: why is a false narrative better than a truthful narrative?
That is a question deserving a truthful response.
