Florida corrections officials are tweaking a plan to replace hard copies of prisoners’ mail with digitized versions, after a legislative committee raised concerns about the proposal that sparked an outcry from inmates’ families and advocates. The Department of Corrections this week published two changes to a proposed rule to address numerous issues flagged by the committee, but the department is continuing to move ahead with the switch. Proposed changes published this week would allow prisoners to receive up to 15 pages of correspondence. Inmates also would be allowed to receive greeting cards that are not larger than 8 inches by 10 inches “when unfolded.”
