In his latest column, PBS ombudsman Michael Getler (right) focuses on controversies surrounding the recent American Experience miniseries on Native Americans, “We Shall Remain.” Getler addresses what he calls a “detailed, non-stop, frontal attack on the program” that arrived in the form of a May 10 letter to PBS head Paula Kerger from a small group calling itself the Wounded Knee Victims and Veterans Association. Kerger had earlier responded to another letter from three tribes in Massachusetts also voicing complaints on the programs.
