Yes, exactly, and that's exactly the point.
Sudden in-custody death from 1979 until now has identified a very similar profile of the person who experiences sudden death in custody, regardless of the restraint methodology used. It is nearly universally the violent, incoherent, agitated, semi-clothed, rampantly destructive individual who undergoes struggle in futile resistance. There's no always, no never, but that is the individual who suddenly and without warning dies in custody.
That is not to say that the individual is at a higher risk from taser application, and that's an important point. In 1980, that same type of individual was experiencing sudden in-custody death, and there was no taser to be had.
