"The gunfire is as far away as the helicopter but is clearly heard."

Not true - it is on the deck just behind the reporters. Before the troops abseiled closer to the reporters they were further away on the helicopters.


"The narrator speaks of unspecified, out of sight injuries, never of incoming fire. Just the cannisters."


True. His comments however are still consstent with the testimony of eyewitnesses on board.

Hence they serve to corroborate the passengers version of events.
