It is cruel AND unusual punishment, not cruel OR unusual punishment. Lethal injection is not unusual and the article even states that it is commonly used. If they think it's cruel - oh well. Don't commit murder and you're all set.
Reporter's behave as if they are scholars on all topics. Glad this one schooled us on the Constitution.
Since hanging was the norm in the time of the Founding Fathers, how could it be deemed cruel and unusual now?????
