perhps something combining a physical hit with a neuro toxin that causes fast paralysis.

so the suspect isnt able to hurt anyone else,

Fast paralysis would most likely also stop the muscles that control
breathing. You would have a non-zero number who would be allergic,
croak, and thus cause uproars. There is a certain small number of people
who die from Tazers, mostly those with unknown (at least to the cop)
heart problems, high on various things (interactions with street drugs
would likely be another concern of neurotoxins).
Heck even just having someone hold them down can cause heart
attacks or positional asphyxiation.
If there was such a thing, the Defense Department would be
working on it.
