The Miami-Dade police department has announced it is reviewing its policy on the use of Taser stun guns after police twice used them in recent weeks to shoot pre-teen children. On Oct. 20 an officer shot a six-year-old first grader with a taser that generated a 50,000 volt shock. The boy was reportedly holding a piece of glass and threatening to hurt himself. Last week police shot and immobilized a 12-year-old girl who was playing hooky from school. Meanwhile in Sacramento California, a man died last week after being shot with a Taser. The man, Ricardo Zaragoza, became the second person in Sacramento County to die after being shot by a taster over the past year. Both victims were on medication at the time for mental illness. The American Civil Liberties Union estimates 76 people have died in the U.S. and Canada after being shot by Tasers since 2001.
