80 Beeps a Day Means No Sleep in NC RHU

I'm a prisoner serving time in Rivers Correctional Institution(RCI), which is a GEO, Inc. prison. It's supposed to be low, but looks like a level five penitentiary.

I'm writing to inform my comrades in Pelican Bay that us comrades on this side of the country in North Carolina RCI are suffering from the same torture tactics in the Restricted Housing Unit(RHU). Yeah, that's the new name of the SHU in here. The difference between our torture tactics is the RHU staff walks by the prisoner cells to press the button on the cell doors every 15 to 20 minutes, 24/7, so 80 times a day.
