The incident:Police say officers only use the Taser when a suspect fails to comply with orders and the officer fears bodily harm. Unlike the use of a gun, which requires an officer fear for his life, the standards for Tasers are lower because Tasers are not considered deadly force.

The big use for tasers seems to be to effect compliance by suspects. Cops used to do that with the old billy club and the slap. They, too, could be deadly weapons if abused, but an officer could usually tailor his blows to prevent severe injury and death. Specific non-lethal parts of the human body were the primary targets.
I reckon a taser might be adjusted to administer light charges, but the difference is an electrical charge is going to traverse a suspect's entire body, finding any susceptibility present.
An LEO can't control where the taser goes, only where it hits. If tasers are indeed capable of causing death by their mere application, this fundamental lack of control excludes their use under existing state statutes, if an officer is not in fear of his life or great bodily harm.
