How are they not all in fucking jail until these crimes are solved?

Let's face it. These are young men that are most likely living on their own in an unfamiliar environment for the first time in their lives. They are living away from their families and probably the friends that they made prior to college. In addition, if they are being exposed to more liberal ideas, and asking questions about psychology, philosophy and religion it can be challenging as well as handling more difficult classwork. I know that I had similar feelings of doubt when I went to college and tried to figure out where I fit in. I stayed an independent because maintaining my grades and scholarships were the primary concern, but I had some envy for the people that didn't have those concerns. By the time that I felt comfortable enough to think about joining a fraternity I was at the tail end of college so it didn't make much sense.
