MEMORANDUM **

Glenn has presented no evidence that any prison official was deliberately indifferent to his safety. See Farmer v. Brennan, 511 U.S. 825, 834-36, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994) (prison officials do not violate the Eighth Amendment unless they act recklessly or knowingly; they cannot be held liable for mere negligence); see also Estelle v. Gamble, 429 U.S. 97, 105-06, 97 S.Ct. 285, 50 L.Ed.2d 251 (1976). Officer Kelly testified that he opened the two cell doors, releasing several prisoners, by accident, and Glenn has presented nothing to cast doubt on Kelly’s motive. Without evidentiary support, Glenn’s speculation that Kelly’s or the other officials’ actions must have been purposeful is insufficient to defeat summary judgment. See Leer v. Murphy, 844 F.2d 628, 634 (9th Cir. 1988).

AFFIRMED.
