My point was that if the passenger action that caused the LEO's reaction came before the video starts, the LEO clearly took too long to act. Therefore most theoretical situations that have the passenger taking any action before the beginning of the video that justify the physical confrontation also require that the officer be so slow to respond that he should not be a police officer.

If someone is a threat in such a way that requires a reaction involving the physical force seen in the video, how long should it take for an officer to initiate such a reaction?
