The discount only arises if you know when into their sentences they were paroled. Was it after 25, 35, 45, or 50 years? If you know the number when, effectively, they were paroled and how long they had served in jail, that will demonstrate whether there was in fact a discount.
Keep in mind that even as the system stands right now, a judge looking at sentencing someone for multiple murders is not going to give the minimum parole ineligibility period. They are going to give an enhanced parole ineligibility period. I would imagine that the parole board, even if a parole board were to look at two cases of first-degree murder, one where there was a single victim and one where there were multiple victims, would be more likely, everything else being equal, to grant parole more quickly to the person who only killed one person than to the person who killed two. It is going to be and is treated, no doubt, as an aggravating factor.
Until you know how long these multiple murderers are actually spending in jail, we are really guessing as to whether there is a discount.
Let me just add this. The sentencing discount is a perception, and I think it's an incorrect perception. It's recognized in law that you can't simply take out an adding machine and add up one life sentence of 25 years for every crime committed or for every offence. In fact, our Court of Appeal for Ontario has gone on about this at length. There was an old case, many years ago, when a fellow broke into 15 cottages. The judge looked and said, well, I would give you eight months in jail for one break-in, so eight times 15 equals x number of months in jail, and that's your sentence. The Court of Appeal said, look, we don't sentence people that way. That doesn't take into account totality. That doesn't take into account personal circumstances, a hope for rehabilitation, or a measure of balance.
That, on the one hand, I think tempers the argument. On the other hand, we need to have that number. We don't have the statistics. The people you are speaking of, this 100 people at 25%, are maybe getting out way later than other people similarly situated who have only murdered one person.
Having said that, we all know that the parole board has some expertise in this. The parole board is not letting out people by picking names out of a hat. Convincing a parole board to be released is a formidable task. When we saw Clifford Olson, that's a lost cause. He's never going to get parole. We trust our parole board to do exactly that. That's exactly what's happening. He's going to die in jail, in all likelihood. In that way, the system is working.
