Not related to topic but thought I'd comment, don't restrain someone who's having a seizure. Move away anything they can hurt themselves on and put them on the ground where they can't fall if possible.
Back to the subject at hand, I agree with Adam that grappling skills would get more use than firearm skills. There are many instances where non lethal methods are more appropriate. These skills are made even more important by the fact that many states don't allow the carry of non lethal weapons such as batons and blackjacks, with some regulating even pepper spray I believe.
