Sam Eilfing’s article in today’s Tyee online news magazine is well worth the read: http://thetyee.ca/News/2013/10/23/The-Innocence-Trap/
In it, he discusses the catch-22 facing all innocent prisoners: If you refuse to acknowledge guilt, the parole board will say you haven’t taken the first step to rehabilitation. Hence, you remain a danger to society, etc etc.
Sadly, that’s only one of the ways innocent “offenders” are disadvantaged over those who are guilty. Another is that, when released, as was wrongly convicted Ivan Henry (@iwmh_Ivan) in 2009, they are simply kicked out onto the street–without, for instance, any of the benefits the guilty receive, such as a community of people afforded by halfway-houses, room and board, financial and employment assistance, etc.
