According to Customs and Border Protection officials, who logged slightly more than half of the 20,000 database hits, only 550 people were arrested or denied entry. Customs and FBI officials did not provide data on the other half of those database hits, but the FBI indicated that the number of arrests were small, the Post reported.

The database is available for use by state, local and federal agencies, and consolidates a number of governmental watch lists, among other sources.
