Since we`re all guessing; here is my guess: He was buckled up, but chose to put his right arm over the belt, so it didn`t cross his chest. When he unbuckled the seatbelt, the seatbelt went back, fastened around him, and when he started to move out of the seat, the retractor didn`t feed him any more belt, so he just thighten it.

And I guess he would have easily gotten out of there alone, but since he probably wouldn`t use it, he "blames" the one that forced him to buckle up.

This is also a norwegian prison:

The thing that many people forget is that spending 10, 15 or 20 years outside of the society is the punishment. Even though you have a nice television or a kitchen, you are still not free. You can`t go out to meet friends, family or wife/girlfriend. Your life is on hold. If you do something stupid as a 19-year old person, I belive that most of the people can change by the time you are 30 or 35. And you still got the punishment of loosing every single thing that every one of us have experienced during our 20`s.
