To that point, I was thinking that.. in some countries, even if you are jailed for murder, after some time served, you may request and can be allowed to take some 'leave' (24/48h). Didn't he get the chance to take any such 'leaves' in the US? I honestly don't know US Justice system. Would there be the chance that his crime was so severe to not be allowed to get a leave at all for 30 years?
