'We were guinea pigs': Jailed inmates agreed to birth control

In a small county in rural Tennessee, inmates were offered 30 days off their sentences in exchange for a vasectomy or a long-acting birth control implant. County officials say it was a tool in the fight against opiate abuse - opponents call it eugenics.

This spring, Deonna Tollison found herself in Judge Sam Benningfield's courtroom in Sparta, Tennessee - a large, neon-lit room filled with wooden pews for the public. Tollison was accused of violating the conditions of her house arrest, the latest issue in a lifetime of trouble, which at its worst saw her living in her car, addicted to opiates.

On the stand, Tollison testified she'd been trying to get her life on the right track - she was off the drugs and raising her two youngest daughters, as well as the daughter of a sister who died in a car wreck. Relapses and run-ins with the law, however, kept stalling her progress, and here she was again, accused of making unsanctioned trips to the grocery store and allowing the batteries on her ankle monitor to die.

She faced the possibility of another stay in the local jail.

"I'm a single mother of three beautiful girls and a brand new grandson. My mother is disabled. My sister is disabled," Tollison pleaded on the stand. "Each and every one of them depend on me because I'm the only one with a [driver's] license. I love my family very dearly...the last four years I've done everything in my power to get my life back."
