landlords who lose security deposits

Here at Docket Rocket, we seem to be serving more and more small claims actions against landlords who refuse to return their tenants' security deposits, sometimes for no reason at all. By San Francisco law, they're supposed to keep the deposits in a separate account. I'm wondering if they made bad investments, lost their tenants' deposits, and invent a pretext to avoid returning the $$$. I'm also wondering if anyone at the SF Chronicle or Examiner is interested in looking into this story.
