Holy **** that's a harsh sentence! Recently this guy shot a 17 year old girl in Sweden, and he was only sentenced to 2.8 years in jail.
I know it's to different penal-systems, but still, the punishment doesn't really seem fit for the crime...
If I didn't know better, I'd say it's because it was Steve Jobs house.
some time ago I had to do some research on how people evaluate different delicts and it turned out that people tend to think it is a bigger crime to take away other people's property than hurting somebody (which was the base theory anyway - and which is also how law is executed). This was in Europe.
