Ron Fineman's On The Record says that Channel 2 aired tape of nude women celebrating Brazil's Carnival on the 6 a.m. news this past Wednesday. A per-diem writer and editor have been blamed and told they won't be hired any more, Fineman reports. On Thursday, says a Fineman source, the staffs at Channel 2 and 9 were given a memo saying that from now on, cameras in the field are to be turned off if people in the background threaten to do anything indecent.
