It will HAVE to be the Feds. I received a reply from the NC Attorney General's office, stating something to the effect of "The Durham District Attorney is an elected official of that county, and we aren't going to get involved." I really didn't expect them to, but you would think they would at least notice the public outcry for justice. This state is the worst in the nation for corruption in state government, from local planning boards all the way up to the Governor.
I have to say this case has been a huge eye-opener.
