On 17 April 2001, James Lee testified before the McKinney panel that the state had given DBT the directive to add to the purge list people who matched at least 90% of a last name. DBT objected, knowing that this would produce a huge number of false positives (non-felons). His testimony indicates the state then ordered DBT to shift to an even lower threshold of 80% match and also include name reversals (thus a person named Thomas Clarence could be taken to be the same as Clarence Thomas). Besides this, middle initials were skipped, "Jr." and "Sr." suffixes dropped, and some nicknames and aliases were added to puff up the list.
