The ideal outcome: Delta operators break in just as the taping starts, with the first knife barely applied to the first peacenik throat. The Deltas kill the terrorists in a hurricane of gunfire right in front of the intended beheading victims. The camera, its operator dead of a .45 bullet in what passes for his brain, continues to roll. A masked Delta holsters his pistol, looks at the camera and gives it the finger, declaring "up yours, Ramsey Clark." Fade to black.
You bring up a good thought. This illconceived notion by these peace activist probably have resulted in activating the real heroes like Delta, or Seals, to attempt something daring if they get a location of these hostages, thus endangering their lives, moreso, and unnecessarily so, than they are already. These Delta guys don't have time for that kind of manufactured shit. Their plate is full.
