If Wilson had a body camera, it might well have been disabled during the fight in the vehicle.
As mentioned, it likely wouldn’t have shown the crucial parts of the fight.
Some in-vehicle cameras would have been useful.
Maybe we need a Google car 360 degree camera for police cars, constantly recording.
Body cameras will only record the image in front of the camera, and sound.
That does not tell the whole story.
Plus, perps will attack the cop just to disable the camera.
