It Could Never Happen
Most of the key plot points in this movie would never happen in real life.
1. US Embassies are routinely prostested by crowds in excess of 10,000 protestors/rioters without being evacuated. The idea of a crowd less than 300 forcing an evacuation is ridiculous.
2. The crowd would have been dispersesd, easily, by the use of copious amounts of CS (tear gas).
3. If the Marines did actually evacuate the embassy, everything on Post 1 (command and control post in the embassy) would have been inventoried. This includes all weapons, log books and VIDEO TAPES! In fact, Marines being Marines, probably would have copied the tape as soon as the got back to the LHA and watched it that evening.
4. In addition to the video tape, the events of the day would have been recorded in the Post Log, which is a legal document. Meaning that the tape would not be the only piece of evidence that proved the crowd was armed and hostile.
5. The radio recording that lead to the “Well, if you got it on tape then I guess I said it” scene could not have happened. The A/N PRC-119 radios that they were using have a maximum range of 5-7 miles. Well beyond the range of the supporting ships at sea.
In other words, none of this could ever happen!
