Koppel has already announced he's going to retire, and he calls his own shots. He long ago decided that he was only going to show up on Nightline when there are stories that he wants told. The B and C level anchors, such as Chris Bury, Terry "Sweet Lips" Moran, Michele Martin, and Chris Cuomo, do most of the work now, while Ted shows up when there's a mucky-muck that makes him/herself available or when there's a really heavy deal going on.
On his way out the door, Ted's either getting careless or bold about letting his biases show. Two of his recent Nightlines were about the success of NRA lobbying despite -- said Ted -- polls indicating that Americans REALLY want gun control, and the think tank he credits with advancing Intelligent Design curricula despite -- said Ted -- academia's overwhelming rejection of it. The tone of both shows was far from complimentary to the subjects; they were more in the spirit of, "How did those charlatans get so far? We've got to stop them!"
"Two of his recent Nightlines were about the success of NRA lobbying despite -- said Ted -- polls indicating that Americans REALLY want gun control."
I think the looters (& rapists) in N.O. make enough of a case against gun control.
