In a worst-case scenario for stun guns, a Phoenix cop kills a suspect with an 84-second tasing
...For reasons that go to the heart of this story, Phoenix police officer Charles Anderson III fired his Taser stun gun into Keith Graff's bare chest from close range and held the trigger for 84 uninterrupted seconds as it discharged 50,000 volts of electricity into the man. That's about 79 seconds longer than it normally takes police to subdue someone shocked by the device. For all intents and purposes, Graff [age 24] was dead when Anderson finally released the trigger. ...
This obvious design defect (not limiting the duration of taser hits) should bring huge liability upon Taser International.
Even if it wasn't obvious in 2003, it absolutely was perfectly duh!-obvious by 2005.
