Some more details on this incident. I found more details on this event from the UK news, not much in American news. I don't know if the Sun newspaper is reliable or like a national enquirer.
Looks like the victim was shot 3 times but not by 3 cops.
Appears 2 cops showed up to a disturbance seen.
This news story doesn't seem to have the domestic violence aspect to it suggested by the RV.
Appears the cops showed because of a disturbance call.
The victim really was crazy, as the RV suggested.
The victim is shot because of his movements, as the RV suggested.
The buildings in the RV drawing are very similar to the apartment buildings in the area of the shooting.
Problem with an RV read like this - to subjective, this sort of event happens to often to perhaps pin down a single event. Though there is some matches with the data I don't know if its enough to prove a viable statistical anomaly. Month of May is not over so who knows, its possible a better match shows up somewhere else this month. But I feel like its this event mentioned in the RV because the video is going viral across global news networks and its a very close match to the RV.
