IMHO, Mike Nifong should have been prosecuted by the Feds for civil rights violations. Why? Because what he did went far beyond someone who overcharged (a bad side effect of the plea bargaining that runs rampant through the criminal justice system). He hid exculpatory evidence and continued on with the prosecution knowing that there was no criminal culpability for the defendants. LEOs are often prosecuted for civil rights violations for excessive use of force. Nifong is just as bad.
As to the OP, I question her ethics as well. Hope the voters who put her in office (or was she appointed?) vote accordingly next time.
