"society demands that murderers are punish hard and punish for prolonged years in prison"
I don't think society is doing such a great job...

Daniel Cassell was convicted of first-degree murder for orchestrating the hit and sentenced to life in prison. According to a Department of Corrections public data base, he's now out on parole.

His hired killer skated because of his youth.

Adams spent three years at McLaughlin Youth Center. He was released in 1981, at one minute after midnight the morning of his 20th birthday -- the longest state law allowed him to be held as a juvenile. The next day, he told reporters the intensive counseling he'd received at McLaughlin did him a lot of good.

"I don't think there'll ever be a day in my life when I don't think about the horrible thing I did," he said at the time "It almost ruined my life."
