They are not a toy for police to play with on the defenseless citizenry. They are not to be used for crowd control, punishment, domination, or whim. Police training needs to expose this misunderstanding that tasers are an easy tool for controlling a person. THEY HAVE KILLED PEOPLE and will do so again.
We need to get this message out there for when the police kill the next person. Then it will be intentional murder rather than an oops. And there will be lawsuits.
Tasers kill, have killed, and will kill again.
Update 12/20: Digby has more.
12/25: And another one. Digby has even more.
