There are a lot of things I don’t understand in this world.

One of them is how a high-priced broadcast celebrity journalist can stay employed by the network that hired after he violated one of the basic tenets of journalism: to tell the truth.

Brian Williams reportedly is out as anchor of NBC NIghtly News. He’s going to be given some sort of undefined “special assignment” slot on the network’s news team.

My strong hunch is that the one-time golden boy of NBC won’t like the demotion. He’ll likely quit to “pursue other interests.” But in order for him to make his exit cleanly and without too much fuss, the network will have to pay him a lot of money to fulfill the terms of his contract.

You know the story. Williams fibbed about being shot down while riding in a helicopter during the early months of the Iraq War in 2003. He embellished the story with each retelling of it in the years since. Then the network discovered at least 10 or so more incidents of embellishments — or non-truth-telling.

Where I come from, that’s reason to get canned, booted, tossed out on your ear.

Brian Williams violated Rule No. 1 of Journalism 101: tell the damn truth.

He didn’t do it.

He’s been reduced to a punch line at parties. Late-night comedians had a field day over his shame. The Internet is still bubbling with fake depictions of Williams storming ashore at Normandy on D-Day and walking on the moon before Neil Armstrong ever set foot on the place. Others are out there, too.

Whatever project he undertakes at NBC will be viewed, I’m quite sure, with plenty of skepticism from a public whose trust in this guy was shattered because he couldn’t carry out the basic rule of good journalism.
