North Carolina executed convicted murderer Willie Brown at 2:11 am this morning. Brown was convicted for murdering Valerie Dixon in 1983 during a robbery. Today's execution made North Carolina the first death penalty state to use a medical device known as a BIS monitor to make sure the inmate remained unconscious during the procedure. The monitor is North Carolina's solution to concerns about whether the standard lethal injection protocol violates the constitutional ban on cruel and unusual punishment. Brown's execution could have broader implications for a nationwide debate on the issue. Rusty Jacobs reports.
