Are broadcasters hindering the ability of first responders?

I think I know why this story has not been widely reported. There have been many stories about how first responders have been unable to get a unified communications tool so that they can communicate especially after 9/11. The culprit could be the media. The broadcasters apparently are unwilling to give up a part of the spectrum that the first responders say they need to provide a unified communications network. The broadcasters want this particular part of the spectrum for digital TV.
