I think one of the biggest obstacles we run into is that people simply don't believe such a thing could happen in America. Nailing the bad guys in Durham now could have a salutory effect on the rest of the Durhams around the country. It sends the message that these kinds of things have no place in America. IOW, clean it up or we're coming after you next.
I can't believe there aren't potbangers outside the DA's office asking him to resign. That's what should be happening.
And nailing the bad guys at Duke which may even take longer could salutory effect throughout the academy. In addition failing to nail the bad guys in Durham and at Duke will encourage the bad guys around the country that it is open season on white males students.
And yet there is puzzlement in academic circles why more than 50% of our students are female and why the trend is toward a higher percentage of females. Duh, you don't go where people hate you for your sex or race if you don't have to.
