Presumed innocent
Zig Dulay's Green Bones from a script by Ricky Lee and Angeli Guidaya-Atienza (story by Joseph Conrad Rubio, Kristian Julao, Angeli Guidaya-Atienza, and Ricky Lee) turns on the premise that a convict judged and sentenced isn't always guilty, and truth is always more complicated.
Having more than passing familiarity with correctional facilities I'd say the answer is: it depends. When you talk to a convict they're always innocent, but when you read their files or talk to someone familiar with their case they're always guilty.
