Tidwell had been on the receiving end of a practice referred to by many in law enforcement as a “medical bond.” Sheriffs across Alabama are increasingly deploying the tactic to avoid having to pay when inmates face medical emergencies or require expensive procedures — even ones that are necessary only because an inmate received inadequate care while incarcerated.

What’s more, once they recover, some inmates are quickly rearrested and booked back into the jail from which they were released.

Local jails across the country have long been faulted for providing substandard medical care. In Alabama, for instance, a mentally ill man died from flesh-eating bacteria 15 days after being booked into the Mobile County Metro Jail in 2000. And in 2013, a 19-year-old man died of gangrene less than a month after he was booked into the Madison County Jail. In both cases, officials denied wrongdoing and surviving relatives settled lawsuits alleging that poor jail health care contributed to their loved ones’ deaths.
