I don't think it's fair to call him a murderer. From what i've heard of the case it seems like MJ was a drug addict who exploited a doctor having financial difficulties and basically just made him do whatever he asked. I think Conrad Murray is right to be stripped of his medical license but I dunno, that long in prison seems a bit harsh. I wonder whether it was ever possible that the court would find that MJ was just a drug-crazed lunatic who caused his own death, always seemed unlikely.
In relation to Conrad Murray again though, it reminded me of a quote by one of my heroes - Jack Bauer
"You can look the other way once, and it's no big deal, except it makes it easier for you to compromise the next time, and pretty soon that's all you're doing; compromising, because that's the way you think things are done. You know those guys I busted? You think they were the bad guys? Because they weren't, they weren't bad guys, they were just like you and me. Except they compromised. Once."
Conrad Murray compromised once....and before you know it he was routinely prescribing drugs that shouldn't have been given outside of a hospital.
