Wouldn't it be evidence to see if she had written about any contacts w/strangers or DW or something?
I've thought about the journal and why no one has brought it up. Dusek wouldn't bring it up because it wouldn't help his case.
I don't think Feldman can bring it up because it doesn't really clear his client, but it makes DvD look bad. It isn't Feldman's job to establish someone else's guilt but to clear Westerfield. I think that if he did try to bring it up, Dusek would object and say it was outside the scope of clearing DW.
