Attorneys and experts ventured deep into the weeds of the available medical literature on the drug midazolam today in federal court, where they are arguing for and against a federal lawsuit brought by Arkansas death row prisoners seeking to make the case that the state's abbreviated execution schedule — which would see seven men executed this month — would violate the Eighth Amendment and their right to effective counsel. Midazolam is a sedative that is the first of a three-drug cocktail the state plans to use to execute seven inmates this month. Today is the final day of four days of hearings in the matter.
