Taser Death Not an Issue in San Francisco [LINK]

The Chronicle reported that one of Taser's own scientific advisers has attributed at least one fatal heart attack in an otherwise healthy person to the Taser. The company has since recommended that police avoid firing the Taser at a suspect's chest.

Zian Tseng, a researcher at UCSF ... cautioned against targeting the chest or firing multiple times and advised that heart defibrillators be made available to revive suspects.

Dr. Byron Lee, a UCSF cardiology professor... warned "That's where the risk happens, where you don't realize these are potentially lethal and they are used in a haphazard manner."
