Glad you're exploring the issue, but... your scenarios are completely contrived. In the ACTUAL scenarios where there is video, we see dashcam video of officers shooting a suspect who is on the ground, and no threat, 9 additional times. We see officers shooting fleeing suspects in the back. We see officers taking 0.75 seconds to decide to murder a "suspect" who is holding a toy gun in a department store. Your story is talking about theoretical risks to interpreting video. In the actual facts, we have already seen that video can add a great deal of clarity to a situation, and often that clarity directly conflicts with sworn statements by the officers involved.
