(AJC) — The prison system began lifting lock downs at four institutions and returning the facilities to normal operations Wednesday and inmate said they were ending their protest for now and reporting to work assignments. One of the organizers of the protest said prisoners are still going to pursue their concerns. If the Department of Corrections ignores their requests, the next protest will be violent, he said. Prison officials did not say what led to the decision to end the lock downs that had been in place since last Thursday. But an inmate at Smith State Prison in Glenville said in a telephone interview prisoners had agreed to end their “non-violent” protest to allow administrators time to focus on their concerns rather than operating the institutions without inmate labor.
