Um, what? Have you seen any cop tasing videos? I've never seen it abused in every video I've seen (hundreds).
The officer continued yelling at him to comply, all the while the man was ablaze, shocked, and bruised.
Cops should have tasers taken away. They believe they are "make people do what I say" devices rather than the rare "make this extremely violent person who is an imminent threat to life and person stop being violent temporarily so other officers can continue to use non-lethal force to de-escalate the situation".
