Secondly, yes, Canadians are fed up with our justice system and the lack of real penalties or penalties that mean something. We have life sentences, but no life sentence exists without the possibility of parole - even convicted serial killers have had parole hearings and some murderers have been released on parole after serving what many people consider only a short period of time. As an example, we've had a man who decapitated another man on a Greyhound bus - he was found not guilty by reason of insanity and yet just a few short years later he is out in the public on day passes and will perhaps be released for longer periods soon. We've also had a doctor who killed his two toddlers in revenge against his wife and he was also found not guilty by reason of insanity and he was fully released a few short years later. And there are untold numbers of criminals out on bail on gun charges who murder while on bail or commit other crimes with a weapon. People here are fed up.
Finally, the link I provided was not related to the Youth Criminal Justice Act, just the issue of capital punishment. This act was revised and adopted in 2012 so I'm not sure if there is polling related to it and I won't bother digging up polls on the previous acts since they're no longer relevant.
