Arkansas inmate Charles Ashford appeals the district court’s 1 adverse grant of summary judgment in his 42 U.S.C. § 1983 action. Following careful de novo review, see Johnson v. Hamilton, 452 F.3d 967, 971-72 (8th Cir. 2006), we conclude that summary judgment was proper for the reasons stated by the district court. Accordingly, we affirm. See 8th Cir. R. 47B.
