It's in the next to the last paragraph.
Sorry, but I don't see anything about the Tailwind scandal in that paragraph. The third one from end repeats his defense ("You want me to read a script, I’ll read it."), but there's nothing I can see about the evidence that he actually helped
write the script.
Perhaps I didn't make it clear. Bozell pointed out Arnett's defense on Tailwind, but failed to discuss the evidence that this defense on Tailwind was a pack of lies.
