Equipping law-enforcement services with Tasers is likely to reduce the number of bullets officers fire from their handguns and therefore the number of serious injuries and deaths. At the same time, it may lead police to inflict an unwarranted amount of pain on individuals who commit only minor crimes.

The broader questions regarding the social effects of stun guns are, however, beyond the scope of this discussion. The two articles that follow investigate the physiological effects of electric shock. The first is by Mark W. Kroll, an electrical engineer who has helped invent numerous electrical medical devices and who sits on the board of Taser International. The second is by Patrick Tchou, a cardiac electrophysiologist at the Cleveland Clinic, who has tested Tasers experimentally on pigs.

So the first person is as far from able to provide unbiased testimony as can be considered possible ("Why, of course they're safe... I'm on the board of directors for the company that makes them.") and the other one is someone who has done exactly zero studies on the effects these have on humans.

Grea-a-a-a-t.
