The jail in Washington, D.C., recently began to allow family members to visit inmates by video conference. The problem is, in-person meetings are no longer permitted. The only way families can see each other now is by sitting in front of a computer screen several blocks apart. Correctional facilities in more than 20 states currently have or plan to have video technology in place, according to a report released by the research and advocacy organization The Sentencing Project. Video technology’s popularity in facilities is driven by a desire to cut staff costs, to reduce security risks created by in-person visits, and in some cases, to raise revenue.
