FYI
He may still!
Technically he didn't have anything to do with it. His crime was that he learned of the plot and didn't tell anyone.
Tough call in these cases, but spending 8 years in prison and three more on parole probably is a fair sentence for someone who wasn't actually involved in the bombing plot. He's not a threat to society, just an idiot who put his loyalty to his friends above the safety of the public.
Still, I wouldn't cry over him if he had an accident, and I'm sure that if one of my kids had been in the daycare, I'd be plotting ways to get at this guy right now.
