I read or heard a report that both officers fired. I believe the first officer was trying to run away as he fired, and the camera was on his chest. It didn't see his gun arm outstretched behind him.
The position he was in was kinda like a driver aiming at the back, passenger-side seat: the body cam would only see the steering wheel.
The only feasible reaolution for this sort of situation is more drastic interventionary measures after earlier incidents. Once he is swinging a hoe at family members and officers, it is entirely too late to expect a non-forceful resolution.
This was not the first time the family called for police to intervene. We need to look at those previous incidents to figure out how to recognize kids that will come to pose a danger to themselves and others.
