Don’t move may not be a valid command when someone is tased

Last night, I was speaking with a close friend of mine. My friend is a CPA and he was telling me about his encounter a few days ago with a police officer who treated him aggressively during a traffic stop despite the fact that he was dressed in a suit. 

During our conversation, we spoke about the Alton SterlingPhilando Castile and Dallas shootings and my friend mentioned something that really struck a nerve; "when a person gets tazed, they can't help but move and cops know that". 

One excuse some police officers state for using deadly force is that even after being tazed, the person wouldn't stop moving. Below is a Taser promotional video. A statement is made that the taser gun highjacks a person's central nervous system, which means after being tased some movements are involuntary and can't be helped. The narrator of the video further states, "It's immediate, it's overwhelming and it instantly stops violent situations".

The guy being tazed in the video is clearly subdued but even after he falls to the ground still makes some involuntary movements because of the electrical current from the taser gun. Certainly, police officers are tazed and may even have experienced being tazed and should know that movement is not necessarily a threat but a reaction to the taze.
