Two more state prisons have acknowledged incidents in which guards zapped visiting children with handheld stun guns, bringing to three the number of facilities where the unapproved demonstration was used on.

On Friday, the Department of Corrections said that several kids visiting Franklin Correctional Institution in the Panhandle on April 24 were shocked by a guard who was demonstrating what corrections officers do at work. On Tuesday, the department revealed that children visiting Indian River Correctional Institution in Vero Beach and Martin Correctional Institution in Indiantown were also zapped with 50,000-volt electronic immobilization devices. The devices used on the children, who are between the ages of 8 and 14, require bodily contact. Used on unruly inmates, the devices usually knock victims to the ground, cause a few minutes of disorientation and leave two small burn marks.

Frank Gonzalez, the owner of Self-Defense USA, a large stun gun company in San Diego, describes the 50,000-volt shock as “similar to grabbing a live wire in your house with a wet hand — like a hard punch in the stomach with the added trauma of electricity running through your body.”

The Department of Corrections did not release the number of children, or their conditions or names. But Matthew Foster, an attorney for one of the children who was injured at Franklin, said that more than six children were shocked at that facility.

His client, a 12-year-old girl, sustained abrasions and trauma when the powerful jolt knocked her to the ground, requiring a doctor’s treatment, said Foster, who asked that neither the child nor her father be named. Her mother works at the prison and gave permission for the demonstration, according to Foster, but the father, who is separated from the mother, did not approve and has sued.

Hey, we’re just gettin’ em ready for their future…you got a problem with that?
