It's been a while since I watched it, but I'd definitely file it under US propaganda since I'm pretty sure they couch the fact that prior to this raid, the US blew up an entire council meeting with helicopter gunships, killing over 200 people including tribal elders who were all vying for peace. To this day the US claims it was a war council and a legitimate target.
So if you want to know why so many people in Mogadishu took up the chance to shoot Americans, now you know.
