So the question is which method will garner more admission of issues? Self reporting (highly unlikely) or the tried and true methods of 60 years of investigative methodology that has been used in the past such as Subject Interviews, record reviews, and reference interviews?
I think we all know the most thorough way the process needs to occur and new methods and database driven re-investigations will prove to not enhance the process if you remove the most tried and true methods and the foundation of federal background investigation to include the Subject Interview, Source interviews, and many of the record reviews in the reinvestigation process.
