death penalty still agree to serve on a jury like that, saying that although i'm really opposed to the death penalty, if the law clearly requires it i can apply the law. but when you get into this debate it becomes very very personal. if you're conscientiously opposed to the death penalty, maybe you hold out regardless of how bad the facts are. on the other hand many people may think life in prison is worse than death, given the fact he'll be probably at the colorado super max in solitary confinement for the rest of his life. you can imagine that all of these debates are going on as to whether death is the greater punishment or life in this kind of facility and whether the death penalty is ever appropriate. >> i know in the state of massachusetts, capital punishment is illegal, but this is obviously at the federal level. i'm wonder just in bigger broader federal cases, paul can you give me examples. i'm thinking of big cases that we've covered.
