An atheist group is blasting Birmingham Police Chief A.C. Roper. The Wisconsin-based Freedom from Religion Foundation complained that Roper is mixing his law enforcement duties, with his work as a Christian minister. The group cited Roper's practice of offering Christian prayers at police gatherings. Roper also works with a group that promotes prayer as a crime solution. The foundation charged that Roper is misusing his position to promote Christianity. A spokesman for Roper said he had no immediate comment.
