He actually used that excuse? "But, but, the story was hard, so I just decided not to let anyone write it..."
Aren't reporters supposed to be able to write stories about stuff they aren't subject matter experts in, by calling up on sources for assistance if need be, more or less all the time? And, of course, in this case two of his reporters already had the story, and the messy wiring diagrams boiled down to a fairly concise punchline.
That's one of those excuses that's so bad it makes things worse.
