People settle lawsuits all the time even when they're likely to win. They want to keep lawyer costs down, they don't want to spend their valuable time in law offices or courtrooms, they don't want to take any chance of getting an incompetent jury, and they want to avoid public disclosure of private information, which could be embarrassing even if absolutely legal. No reason to believe Bill O'Reilly doesn't fall into one or more of those categories.

But this letter was about Bill O'Reilly's supposed slander of the Red Cross. The evidence is clear that the writer's memory of the time is clouded. Or it's a matter of haters gonna hate. Which reminds me of the constant hating of President Trump by garycrum, although to his credit he hasn't dissed on Trump yet in this thread.
