“Hate in America,” the Investigation Discovery program, produced in partnership with the Southern Poverty Law Center, gets closer to the real-world consequences of intolerance and discrimination. Here, the victims of bias crimes, or their survivors, do the talking. Mr. Harris revisits three crimes: the race-related murder of James C. Anderson in Mississippi in 2011, the shootings at a Sikh temple in Wisconsin in 2012 and a homophobic attack on two men in Manhattan in 2013. Much of Investigation Discovery’s fare is lurid and lowbrow, but “Hate in America” is an exception. Mr. Harris details the crimes and conducts sensitive, often moving interviews with those who were affected. Why didn’t you just walk away, he asks Nicholas Porto, one of the men beaten near Madison Square Garden after he responded to gay slurs being shouted at him and his boyfriend. “Because the more you walk away,” Mr. Porto says, “sooner or later you run out of places to walk to.”
