I can't imagine the third guy in line, hearing her scream and cry, begging them to stop, would get excited. I understand that there are sociopaths out there that enjoy that, but I can't imagine five (or however many) of them in one room from one high school. Also, to the extent date rape happens, I imagine guys are emboldened by the lack of witnesses - he said she said. This wasn't that. Five guys, willing to listen watch and participate in felonies, and willing to do it in front of witnesses?
Not saying it didn't happen. Just seems bizarre.
