The Rev. Donald Wildmon's American Family Association has urged members to protest against CBS's decision to air an updated version of its 9/11 documentary in which firemen and other emergency workers are seen swearing. Although the program had aired previously without challenge from the FCC, the commission has since ruled that similar language used by blues musicians in a PBS documentary was indecent. In its letter the AFA urged members to send complaints to the FCC and their local CBS affiliates. CBS said in a statement: "In order to ensure that viewers are aware of the language, we will include warnings in the broadcast, and Robert De Niro, who will again serve as host in a newly taped introduction to the program, will also alert viewers to the graphic language. This will allow ample notice for viewers to seek other programming if they feel this broadcast is not appropriate for their household."
