Marion Jones had a newsconference in SF yesterday. She lambasted USADA and said she'd refuse to participate in their "kangaroo court."

She had one minor mistep, where she gave slightly evasive and inconsistent answers to reporters' questions about ZMA.

The key to the feds' case will be finding at least one knowledgeable witness to testify against her, either saying directly that she used banned substances, or at least providing an explanation for the coded notations in her BALCO file.

There are three witnesses who are working on plea deals: Conte, C.J. Hunter (Marion's ex), and Trevor Graham (her former coach).
