BOP should reassess its policies to ensure that SHU round documentation is preserved for the possible use of such documentation as original evidence in criminal and administrative investigations and proceedings. As part of this reassessment, the BOP should, among other things, consider (1) adjusting its records retention schedule for SHU round forms; and (2) amending its policies to ensure that staff responding to crime scenes associated with inmate misconduct also collect evidence of potentially related staff misconduct, such as SHU round documentation, and account for the possible use of such evidence as original evidence in criminal and administrative investigations and proceedings.
