We have an elaborate process of verifying all facts. It's multi-layered. However, even with that check and balance, it would have been impossible, in this case, to catch this error, because, as I said a few moments ago, what happened here is that the script that was produced and approved by the producer was later altered, and altered in two ways, by the reporter and by the editor.
Again, this is something I have never seen and I have no experience dealing with in my 33 years in television news.
