Coy Treat filed a pro se civil complaint against the United States under the Federal Tort Claims Act (FTCA), asserting that he was attacked by another inmate and suffered injuries as a result of the negligence of a doctor at the Medical Center for Federal Prisoners and other prison personnel. The district court 1 granted summary judgment for the United States, and Treat appeals. Having reviewed the record de novo, we affirm for the reasons stated by the district court. See 8th Cir. R. 47B.
