Life sentence with chance of parole?

I was just watching a show on discovery id and at the end it said the cunt was sentenced to life in prison with the chance of parole in some year, I don't recall (been denied twice).

I know I've seen it before but it never really registered. But how the fuck can you be eligible for parole when you get sentenced to life in prison?

I know that the people rarely ever get granted parole but whats up with that? Phone Post
