Tasers have been misused or linked to accusations of torture or corporal punishment in U.S. prisons and jails. Reuters identified 104 deaths involving Tasers behind bars, nearly all since 2000 - 10 percent of a larger universe of more than 1,000 fatal law enforcement encounters in which the weapons were used. Of the 104 inmates who died, just two were armed. A third were in handcuffs or other restraints when stunned. In more than two-thirds of the 70 cases in which Reuters was able to gather full details, the inmate already was immobilized when shocked. Tasers have high potential for abuse" behind bars, said U.S. Justice Department consultant Steve Martin, a former general counsel for the Texas Department of Corrections who has inspected more than 500 U.S. prisons and jails. "When you inflict pain, serious pain, for the singular purpose of inflicting pain ... it meets the definition of the legal standard of excessive force, but it's also torturous." San Bernardino County paid $2.8 million this year to nearly 40 current and former inmates to settle a series of lawsuits that included allegations Tasers were regularly used for torture at the county's West Valley Detention Center. The suits alleged an array of abuses at the 3,347-bed jail ... including guards stunning inmates in the genitals. Inmate John Hanson testified he was shocked nearly five times a day from February to March 2014 in "surprise attacks" as he delivered meals to inmates. Deputies were "truly enjoying the control and affliction of pain," he said.
