Response:  From what Steven Brill said in his article, it seems prosecutors did release information that would be protected by grand jury secrecy--Starr disagrees because he is taking a very narrow view of grand jury secrecy.  The usual standard is that secrecy protects any information that would reveal what (and who) the grand jury is investigating, and the information Starr apparently released would do that.  Starr seems to argue that secrecy only protects what actually went on in front of a grand jury, like what a witness testified to.   While a court might very well disagree with him, and find that he violated secrecy, it is very unlikely that the matter will ever be pursued to the point that a court rules on it.
