Not an admin but before one of them marks this invalid and closes the thread, type "status" into console to pull up everyone's name and steam ID while someone's freekilling in case they disconnect afterwards. Also you need a demo in the case of a mass freekill. For all we know, NUT was supposed to kill all reds because it might have been out of cell rebel day or something. Without the demo which outlines the whole round it's impossible to tell.
