Only with a very perverted view of what the justice system is good for.
You've found a prominent case of one very terrible person being treated better than he deserves. Yes, I actually agree with that, he shouldn't be getting video games.
On the other hand, do you really want me to start pointing out all the failures of the American justice system? Personally, I'd rather we occasionally show more mercy than we should than have a system like in the States where one out of a 100 people are incarcerated for bulls**t drug charges, three-strikes laws, etc.
I'm very aware of the problems with the American justice system. Drug possession and use should be treated as a mental issue. It shouldn't result in incarceration. I also do not support three-strikes laws.
As for those convicted of first-degree murder, I do believe in a harsh penalty. I do think the death penalty is wrong (and I've pretty much always been a staunch opponent), but I would honestly support that over a 21-year penalty with perks for someone who killed 77 people. I personally would support life without parole as the maximum penalty with absolutely no entertainment options.
