The photos are not something that any parent or school official wants to see: college athletes in apparent initiation scenes involving degrading costumes, excessive drinking, sexually suggestive poses with strippers and fellow athletes, and a blindfolded woman with her hands tied behind her back being led down a staircase. Posted in recent months on Internet sites such as Facebook and BadJocks.com, the photos from more than a dozen colleges are bringing another flurry of attention to hazing rituals. Investigations and disciplinary actions are under way against teams ranging from men's baseball at Elon University in Elon, N.C., to women's soccer at Northwestern University in Evanston, Ill.
