Well, most LE Agencies have a "NO PRESS" policy that prevents officers from making comments regarding ongoing investigations. Since he was walking out of the GJ the investigation was still ongoing. I'm not defending his mistake. However I am defending not making a comment that could cause him even more disciplinary action from his agency.
The press always makes a big deal out of this. They show an officer saying "no comment". Well no #$%@ no comment. Do we ever say anything to them. No. We have an officer designated to handle those matters.
