A city investigation into allegations of brutality,by Ann Arbor Pólice officers during the search and detention of a Philadelphia musical group May 10 has concluded that the officers are innocent of the misconduct charges against them.' The report, which was requested by Mayor Wheeler and which has not been publicly released, states that the pólice otficers neither participated in nor observed any acts of brutality against members of the Blue Magie band. However, the finding was disputed by Detroit attorney Ivan Barris representing Blue Magie: "I expect nothing but stonewalling from the Ann Arbor Pólice," he told the SUN. Meanwhile, Sheriffs deputies William Tommrlein a"hd Randel Evans, both fired for conduct during the search of Blue Magie, are appealing their dismissal and are scheduled to go befare an arbitrator August 22. Both federal and state criminal probes are still in progress into the conduct of law officers during the search. Attorney Barris expressed confidence in the conduct of the federal probé, but had reservations about the County Prosecutor's investigation: 'Tm more hopeful in the area of the federal officials than I am in the area of local officials," stated Barris, "but I'd like to be pleasantly surprised. While all the right words have been said by (Prosecutor William) Delhey and others, action on their part seems to be lacking."
