I lived next to him, interacted with him when i lived in the same duplex as him from May '08 - Mar '09. I saw ZERO signs of this, having been inside his side of the duplex multiple times. saying this started back in '08 is a horrible assumption, during the time i knew and interacted with him i could easily say that he was a model citizen. But it is a college, very liberal college at that; You have to be kidding me to think that there is a student on campus in IC that has not at least ONCE been exposed to this stuff.
Unless you go to college for all the right reasons, and live at home with your parents still... then you will be at a social function and be exposed to this at one point or another in college. But it is who you are in that moment that determines who you really are.
