Can anyone explain this to me?

A parole board in Alberta, Canada, has granted parole to a convicted sexual predator less than a year into his nine-year sentence just a month after it rejected his previous parole application: http://www.cbc.ca/canada/montreal/story/2008/07/18/predator-released.html. I'll try to leave aside for the moment my personal opinion that sexual predators, particularly those who prey on children, should NEVER be allowed out of jail once convicted, and that the original nine-year sentence was pathetically inadequate. HOW can they justify letting out this creep less than a year into his sentence, and after parole was just denied to him last month, and at which time it was determined that he was likely to re-offend? HOW??????
