******In reaction to an independent BBC review on taste and standards commissioned after offensive comments about actor Andrew Sachs created a public outcry, the BBC Trust has said that the most offensive language should only be used in "exceptional circumstances" on BBC One between 9 and 10 p.m.******Editorial guidelines should clarify that BBC should not make programmes that "celebrate or condone gratuitous, aggressive, intrusive and humiliating behaviour," the Trust ruled, recognizing that "licence fee payers can distinguish between comedy and satire, which they appreciate, and unjustified humiliation, of which they disapprove." ******The study, which polled 2,700 participants, finds that viewers don't want more censorship or regulation.******"Most people value the creativity of the BBC and accept it may sometimes result in people being offended."******What do you think? Should BBC allow swearing on air?
