CrimProf Blog speculates on the likely leakers in the BALCO case. (Hat tip, Instapundit.) He's narrowed it down to either one of the defendants or someone on the government side. I like his reasoning for ruling out the defense lawyers.

The defense attorneys and the defendants might have had an incentive to leak, since Bonds denied knowledge that the substances were steriods and said that he didn't think the BALCO defendant from whom he received the substances would have provided him with illegal steriods. It seems perhaps unlikely that one of the defense attorneys leaked the information, however, because leaking secret grand jury evidence to the media, and then moving to dismiss charges by blaming the government for the same leak, is a high risk venture that would take serious moxy if not insanity. Too much to lose, not enough to gain.
