Excerpt:
The National Geographic Channel has beefed up security at its Washington headquarters after being "bombarded" by threats over its upcoming film, "SEAL Team Six: The Raid on Osama Bin Laden," a source said yesterday.
The movie has prompted enough threats from what one source called "Muslim extremist groups" that the network felt it had to take the action.
"They have been bombarded with phone calls and blog posts, saying that anyone airing a film like this is asking for trouble," the source added.
