Liberal Lies: Tasers kill Truth - Not one documented case ever.

  Tasers have been used on over 100,000 volunteers, including individuals involved in training seminars and research experiments, and involved in over 70,000 actual field uses during police encounters. - United States Govenment Accountability Office (GAO)

And not one single death in rational, healthy, sane volunteers. Why is that?

Law enforcement authorities face similar challenges in the field. They are often first on the scene, and must make important decisions with regard to their safety and the safety of everyone involved. The etiology of the delirium, the individual's underlying medical problems or metabolic milieu, or the severe co-morbidity accompanying cocaine/amphetamines, not to mention the individual's personal arsenal of dangerous weapons, simply cannot be determined before incarceration, cooperation, or submission are mandated. Many chronic stimulant users, for example, have clandestine cardiac disease, waiting to emerge as a lethal dysrhythmia when the milieu is right. 

Chokeholds, hastily delivered gunshots, hogtying, and clubbing have been largely abandoned, and generally are believed to constitute unnecessary and unusual force. First responders who must quickly incapacitate a dangerous criminal have turned to the conducted electrical weapon, often called a stun gun but most commonly called a TASER - source

Tasers save lives. An Officer no longer has to get close to a possibly armed, certainly deranged individual that could possibly gain access to the officer's own weapon during a close struggle.

Upon examining the 72 mortality cases appearing in the Amnesty International 2004 report on stun device use, in no instance was stun employment implicated singularly as the cause of death, although the application of stun devices could not be ruled out as a possible contributing factor. These cases showed that other contributing factors, including pre-existing morbidity (such as heart disease), excessive drug ingestion, and multiple force applications (baton, wrestling, stunning) could have also led to the deaths. - Potomic Institute

Tasers have not been found as the cause of death in one single death of a person on this planet. They have only been listed as a secondary contributing factor.
