Prison regulation of gang insignia and materials clearly prohibited possession of photographs of people in the gang's colors and making hand-signs associated with the gang; no reasonable guard would be unaware that there materials were encompassed by the regulation.
Where a previous penalty proceeding is vacated upon review, and in the subsequent penalty, credit is given for the time served of the earlier penalty, the first proceeding is not a basis for a due process liberty claim.

Circles added to photographs examined during the proceeding were harmless, as the expert earlier reviewed the photos without the circles.
Talking over the presiding officer and waving his finger at her was sufficient basis to remove the prisoner form the proceeding.
