From Brian Williams at Daily Nightly blog…
LATE DEVELOPMENT:
NBC News has indeed received
what I would call a “multimedia manifesto” from the gunman. We
received it today, and immediately handed it over to Federal law
enforcement authorities. We are still going over our own copy — its a
lot of material — we are talking with law enforcement, our own
standards people — and Pete Williams, our Justice Correspondent, will
join me live on the broadcast to go through the material.
UPDATE:MSNBC has a photo up online
