Private Lynndie England - Graner's one-time girlfriend - was convicted for conspiracy, maltreating detainees and committing an indecent act, and jailed for three years.
Harman appeared in one of the infamous Abu Ghraib photos, crouched behind a human pyramid, smiling, giving a thumbs up with Private Graner, arms folded behind her.
Defense attorney Spinner pointed out that at least two others who witnessed the abuse or had seen the pictures felt physically threatened by Private Graner and others and so remained anonymous or silent.
