The majority, while characterizing the matter as “critical,” says that there is “nothing in the record to suggest that Mr. Bucklew will be capable of experiencing pain for significantly more than 20 to 30 seconds after being injected with pentobarbital.” Ante, at 26. But what about Dr. Zivot’s testimony that the time between injection and death “could range over a few minutes to many minutes?” App. 222.

Ante, at 27. But immediately following his prediction that the time between injection and death could range up to many minutes, Dr. Zivot stated that “beginning with the injection of the Pentobarbital solution and ending with Mr. Bucklew’s death several minutes to as long as many minutes later, Mr. Bucklew would be highly likely to experience feelings of ‘air hunger’ and the excruciating pain of prolonged suffocation.” App. 222 (emphasis added).

The majority also justifies its refusal to credit Dr. Zivot’s testimony on the ground that Dr. Zivot gave a response during his deposition suggesting that he misinterpreted a
