No, it was more than just saying that the FBI leaks haven't stopped. It was a reiteration of the 1st press conference; it was detailing the investigation, how his girlfriend and his friends and associates are being treated, how he's being followed, and harsh criticism of the FBI and AG Ashcroft. Unfortunately, the more he talks, the more the FBI and Ashcroft are going to put pressure on him.
I understand that his lawyer is a civil attorney. A criminal defense attorney would've told him to keep his mouth shut.
It was made clear at Hatfill's first conference that he had hired a criminal defense attorney by that point. He did so immediately after a criminal subpoena was served on him by the FBI at the time of the search of his apartment that was done with all those media guys present.
