A coalition of Minnesota human rights activists say tasers are too dangerous. They're urging some Metro - area police departments to stop using the stun guns. The coalition includes the University of Minnesota human rights program, the Center for Victims of Torture, and AMinnesotaesty International. They say stun gun use should be suspended until more independent safety research can be done, and until there are strict, uniform guidelines governing use of stun guns. A coalition letter to police chiefs in Minneapolis , St. Paul, and Roseville, says more than 74 people in the U.S. have died after being stunned by tasers. St. Paul police spokesman Paul Schnell says the chief is aware of the concerns, but the department will continue using tasers.
