State officials should not use tasers as devices to compel positive acts. I have made and explained this point elsewhere, but I believe that I have failed to do so previously in this 'blog.
When tasers were introduced to policing, they were presented to the public as devices to stop attackers, without potentially lethal force. It would take some contrivance to present a situation in which such use of a taser would not be preferable to lethal force.
But tasers also inflict pain. And police officers quickly began using them to hurt people until those people complied, even when compliance was a positive act, such as moving one's body in some way. The pain inflicted by a taser is sufficiently severe that it will cause people to act in ways that will lead to their convictions, as when a taser was used to induce a suspect to produce a urine sample. Used to motivate behavior, a taser is a device of torture. Judges have acquiesced to this use of torture to compel positive acts. Almost no one speaks out against it. The taser has become a socially accepted device of torture.
