Another way to look at it is that they already had a media company with an established viewer base and reach, and they used it to broadcast the investigation details as widely as possible while still maintaining privacy for everyone involved. What would you have them do, get the investigation company to post the “all clear” message somewhere that nobody will ever see it? They already had a soapbox, so they used it; They likely didn’t see any need to reinvent the wheel when they already had a way to broadcast the message.
