You guys are all crazy.
Isn't even a noose. Se was crawling on the latticework, attempting to hang a pinata from the loop, and fell. The girl under her was sitting on the stoll, and when she fell, the other girl stood up, knocking the stool over. She didn't fall backwards out of the loop, because she managed to grab onto the rope. This meant that she strangled slowly, unable to drop to the floor out of fear of death (the floor looks to be about 10 feet below her, and she wasn't bright enough to realize that ths would probably just break her legs).
She was being attacked by a serial killer, who ws going at her with a knife. She ran into a nearby phonebooth to protect herself better, and managed to hold the door shut against his best efforts. It was then that a helpful bussinessman came by, scaring off the assailant. Seeing she was quickly loosing blood (the wide, thick spray patterns mean that the killer must have hit a major vein), he attempted to perform first aid. However, as we can see, he could not get to her, as her log was locked in a position that prevented him from opening the door. So, he attempted to break the glass. We can see that this didn't work out as planned. Her blood was seeping out of the booth, and he, not realizing the blood on his shoe, turned to find another phonebooth, to summon aid. At which point, he was struck by a car, and he is now recouperating in the hospital.
If I weren't here, you might have convicted an innocent citizen.
