John Lennon's Killer Denied Parole Again

I know this maybe a bit of a different topic than usual, but I thought it was interesting...

John Lennon's killer has again been denied parole, nearly 30 years after gunning down the ex-Beatle and iconic musician outside the singer's Manhattan apartment building.

A parole board today denied Mark David Chapman his freedom after an interview at Attica Correctional Facility in upstate New York.

It was Chapman's sixth appearance before the parole board since becoming eligible for release in 2000. He's eligible again in 2012. Chapman had been scheduled to appear last month, but the hearing was postponed by parole officials. They said at the time they were awaiting additional information. It's not known what that information was.

Chapman was sentenced to 20 years to life in prison for shooting Lennon four times in December 1980. Four times, as if he were an assassin. He was an assassin.

So, what do you think? Has he served enough time? Or is he hopelessly mentally ill and dangerous? I wonder what the experts say.
