An element that adds to the persuasive strength of Mr. Kendall's letter is that the prosecution's office is one of the most obvious places to look for leaks, since it has placed little evidence before the public since the initial Lewinsky bomb was dropped two weeks ago. With its case being developed behind the closed doors of the grand jury, Starr's investigation has seen the release of poll after poll indicating the American public seems to perceive Starr's apparent lack of progress as an indictment of the overall legitimacy of his investigation. However, Starr's office is but one of the many involved parties which might have an interest in leaking grand jury testimony. For instance, the White House itself might decide to leak self-damaging information so that it could then blame Mr. Starr's office. But the fact is that anyone involved in this case, no matter how tangentially, might want to endear himself or herself to a journalist by providing grand jury testimony.
Some sources simply believe in whistle-blowing.
Others expect the journalist to return the favor sometime in the future. The possibilities are endless. Ultimately, no source would provide such information without an agreed guarantee of anonymity. Since no journalist is going to reveal a source after making this guarantee, it is highly unlikely much will come of this latest exchange between the White House and Kenneth Starr.
