Cincinnati's police chief says stun guns have worked in nearly all attempts and very few suspects have been hurt by the jolts of electricity since city police began using the devices in January. Details of the first report on use of the Taser guns by Cincinnati police were provided to a City Council law committee yesterday by police Chief Tom Streicher. He says officers who were not carrying the weapon were able to get suspects to comply just by claiming they had a stun gun and might use it. The weapon fires two barbs that attach to a suspect's skin or clothing. They send 50-thousand volts of electricity to temporarily immobilize a suspect long enough for officers to gain control.
