The pertinent summary of his case, by Justice Thomas writing the majority opinion for the denial of Landrigan's habeas appeal:
Jeffrey Landrigan was convicted in Oklahoma of second-degree murder in 1982. InThe last minute legal wrangling consisted of Landrigan's lawyers majoring in minors by attempting to argue that the execution would be cruel and unusual because Arizona apparently obtained the lethal drug dose from a non-FDA approved source in Great Britain.
1986, while in custody for that murder, Landrigan repeatedly stabbed another inmate and was subsequently convicted of assault and battery with a deadly weapon. Three years later, Landrigan escaped from prison and murdered Chester Dean Dyer in Arizona.
I dunno, we've had Supreme Court justices suggest that our Constitution be interpreted by looking to the laws of other countries. If we can safely look to England for guidance on interpreting our Constitution, why can't we borrow some sodium thiopental from them to execute our murderers?
Landrigan's case proves yet again that there are no possibilities available to us to render certain offenders harmless, and that the only way to protect society is to execute these offenders.
