[The Cobb County Courier has a policy of withholding or redacting the name of suspects unless and until the person is convicted in a court of law or enters a plea of guilty. All suspects are innocent until proven guilty, and the internet has no effective way of removing reports of arrest if the person is exonerated. We do make exceptions in high-profile cases or charges against public officials where exoneration is likely to be as widely publicized as the initial arrest

We also withhold names in traffic incidents when it is uncertain whether charges will be filed]
