That research actually comes from the national survey we did of crown and defence counsel, where we looked at how it's taking longer to process these cases than it did 10 or 20 years ago.
You're seeing vastly more people going to trial and challenging the charge. You're seeing more cases lost at trial. You're seeing fewer cases pled. You're seeing caseloads of crown counsel increase dramatically.
I think all those things contribute to an erosion of the deterrent effect. If the public doesn't believe they'll necessarily be convicted, which is why they're willing to go to trial, I think that's a strong statement about how deterred they are.
