>> well, the main issue in the case is the use of the drug midazolam.t is not an anesthetic, and it is not a pain reliever. what happened in the clayton locket case, we saw how midazolam really works because of the mal-administration of the drug because the medical team was not able to access the vein. >> you have to remind us why we're here. you mentioned one case, but i know the case that many will recall, and you were involved in that as well. the joe wood case in july. remind our viewers how horrendous a process that was in putting him to death in arizona. that took two hours? >> well, the state of arizona used a two-drug formula of midazolam to carry out the execution. 12 minutes into the process mr. wood began to breathe. he was gasping and gulping, and that lasted for an hour and 40 minutes. it took almost two hours for mr. wood to die. >> sounds to me there is some experimentation going on here. >> well, that's exactly what's going on. the states are experimenting with different combination of drugs to carry out the lethal injections. historical
