In Virginia Beach, a city on America's east coast, 260 of the roughly 1,400 inmates in the county jail are being treated for mental illnesses.
The local sheriff, Ken Stolle, told the BBC that most weeks, he has more inmates in his jail suffering from mental illnesses than the state's system has beds.
That leaves Mr Stolle feeling as though he's in charge of the default mental institution for the area.
"Most sheriffs that I know feel like this is a problem that needs to be addressed by the state and that we shouldn't be the provider of last resort. That's what we feel like we are right now, " he says.
"If the system fails to catch these people in a safety net, they end up in the jails."
The jail has its fair share of rowdy, unruly criminals. But it's the mentally ill inmates who Mr Stolle loses sleep over.
"Ninety percent of my assaults on deputies last year were committed by mentally ill inmates," Mr Stolle told the BBC.
"I've got a problem there in the security and the safety for my deputies."
Some inmates have thrown excrement and urine at staff, others rush the doors when they are opened, injuring staff in the process.
But Mr Stolle also worries about the harm these inmates do to themselves. The jail's small medical centre sees a shocking array of conditions. Fist tap Nana.
