if we go by what her mom is saying or what is said in the newspaper then i have to say that the guys were really dumb to have planned it like this. did they really think they could have gotten away with this! she was their class fellow!!
if people have the same mentality as PM or zobia, yes they could have gotten away with this, and probably still will. apparently no one of good character is expected to report such a crime. look at how much crap is being slung their way already for doing so.
