I agree, fuck these tasers!!! I think they should have shot him instead. j/k
Seriously, 12 times is way too much. I think tasering him once or twice was warranted, and when that didn't work, they should have stopped.
I think maybe next time he has a seizure, his parents and loved ones can take him to the hospital instead, because we can't have him punching those that are trying to help him. But since that will never happen, I don't know what they really can do, other than roll with the punches and lay off the taser. Maybe he could have some sort of medic-alert bracelet that can alert the paramedics to his combative nature during seizures.
