I have videos of swat being escorted through the lobby before any shooting took place, a sniper on a shed further away from the building and a taxi driver at the front of the building and you can clearly hear 2 belt fed machine guns going off. They were shooting at different rates, so they were different models. Pretty sure our government was trying to assassinate that arab leader and took advantage of the situation to call for gun control(never let a good crisis go to waste).
