Aliza Kaplan spends most Wednesday nights inside Oregon State Penitentiary, the state’s only maximum-security institution. “OSP was built so long ago that it was not built for the prison population we have now,” she told Filter. It recommended that the department “develop and implement a plan” for emptying “unsafe facilities, such as the Oregon State Penitentiary.” For her, this is what the feasibility study and plans for new construction don’t address. “We have an aging prison population that needs attention right now.”
