Unless the girl was drunk since she met the guys that day, she went to a hotel room with them. What was she expecting, tiddly-winks? I have no problem in placing the fault equally on all present. The punishment by law, however, is not equal. She should get a record of being a slut.
That is apparently what young girls aspire to these days. Haven't you seen the tee-shirts saying "porn star", etc.?
That's what many teen girls aspire to these days.
