There's a larger issue, though. All laws ultimately are enforced by people with guns who will do violence up to and including death if people don't comply. Some laws are less likely than others to result in death (e.g. drug laws vs. securities fraud), but "is this law worth killing for?" is a question we all should ask when considering what the law should be.
If the threat of a taser is a threat that warrants lethal force in self defense, the police are reaching for them far too quickly when they deal with people who are non-compliant. It takes very little provocation for most police officers to deploy their taser. I believe they are almost always used against unarmed people (armed people get shot, not tased).
