In fairness the article doesn't go into what the findings of fact actually were.
The jury found him guilty of manslaughter, but there's no speculation as to how they came to that determination. It's not fair for us to speculate what that may have been without all the facts.
According to this article (again it's not nearly all the facts)
http://www.calgarysun.com/2014/02/19...d-her-to-death it sounds like his girlfriend was very abusive. Again, I'm not defending the guy, I have no idea what all the facts are.
All I'm saying is we can't simply jump to a conclusion that the legal system is broken because of an article in a newspaper with zero context, especially when a jury of 12 people (6 men, 6 women) found him guilty of the lesser charge.
The sentence has to reflect manslaughter. A judge can't sentence someone to prison time for first degree murder when the guilty verdict is for something else, that would truly be a broken system.
