CNN Propaganda Piece?

The following is a it's live video of an attack on a 911 memorial service in Afghanistan, on CNN. It shows CNN reporter - Anderson Cooper in Afghanistan talking to the public, but strangely all the troops rush off screen and man their battlements. And then they cut to the troops firing at an unseen enemy. Here is the video:

When searching forAnderson Cooper I came onto this site: The secret CIA past of CNN's Anderson Cooper.
This got me thinking, if you want to promote fear to the general public and show that terrorist are still out that, then what the best thing you can do? The video shown is strange, it too screams of 'setup'...
Another Site has this report as well: Rense.com

The following can best sums it up from Hsing Lee

We're supposed to believe that the Taliban was good enough to allow Cooper the time to give his set up on live TV before they started firing, and we're also supposed to believe that CNN just happened to have cameras perfectly positioned and ready to record the American soldiers firing those bigass guns at an enemy that we never get to actually see.
