The Supreme Court will decide on the constitutionality of the death penalty by lethal injection.

Lethal injection was invented right here in Oklahoma. We had it first. And the protocol invented in Oklahoma is the same three-drug cocktail still used in 37 other states:

• sodium thiopental to knock 'em out
• pancuronium bromide to paralyze 'em
• potassium chloride to stop the heart.

If the court rules against the injections, Oklahoma's backup execution method is the firing squad. The Supreme Court found that constitutional in 1878.
