Why would the GJ put a gag order on Boylan? All the other GJ witnesses--Angela R., Deana Newhouse, Thurber, Moul, etc.--have been flapping their lips all over to the media.

Mary Katherine has been the most closely guarded asset in this whole investigation. Media has been allowed NO access to her, other than a single photograph of her and Elizabeth together. Reports are that police interviewers have only had access to her while in the presence of her mother. Now that Boylan has finally been allowed access, we find that the strict rules of secrecy continue. Whatever Mary Katherine brings to this investigation must be EXTREMELY SENSITIVE information......but sensitive for WHOM???

Given Boylan's history of work on serious investigations, her lip-flapping is likely to be given a lot more credence than the lip-flapping of the others you mentioned (though I can't remember who Deana Newhouse is). Moul is an auto mechanic, Thurber is a low-life, and Angela Ricci is an ex-con. I would assume this is why the authorities are more interested in curbing Boylan's lip-flapping than the others.

Because, like I've been saying for a long time, they know who the kidnapper is but they don't want you to know?
