Not really. When an inmate goes before the Parole Board, the whole thing is on him. There are no lawyers or advocates. It is strictly the assessment of the behavior while incarcerated and if they show enough contrition and remorse. Sometimes even that isn't enough. There is no magical way to get paroled, the inmate has to set the table with good behavoir and completing programming that has been recommended.
