I don't know enough about the Callow decision to make an intelligent comment, but I'd like to make this point. Dangerous offenders, of course, do in fact get released. They become eligible for release on day parole four years after they have been arrested, and they become eligible for release on full parole seven years after their arrest date, assuming they've been kept in custody, as most of them have. Those are dangerous offenders I'm speaking of, not long-term offenders. The average release date of those who do get released--and not nearly all of them get released--is approximately 13 years. That's the evidence, I've been told, which, curiously, is the same average release date time for an individual who is serving a life sentence with a 10-year minimum parole eligibility. Those individuals typically convicted of second-degree murder are on average released at the 13-year mark, if they are in fact released. There is at least one and maybe two dangerous offenders here in Ottawa now who are on release. One of them seems to be rehabilitated--the one I know about--and maybe they both are.
