Folks, I am going to close this one. There has BEEN a thread running on this for some time. The link cited is very misleading- what they are calling breaking news was an NBC video from the day of the shootings. There is also this note at the bottom of the writeup-
"Editorís note: The language about the weapon in the video was altered to reflect that it is speculation"
What we have here is... failure- to communicate.
