What price will teens and college kids pay to belong to a popular clique? Al Roker hosts “The Horrors of Hazing” (9 p.m., Court TV), a grim look at conformity run amok. The hour-long expose focuses on the murder of Alfred University junior Ben Klein. He was beaten to death after revealing the secrets of his fraternity’s hazing rituals. Roker travels to other schools where students, male and female, have been intimidated by violence after leaving fraternities and sororities.
