The release of thousands of pages of documents related to the late sex offender Jeffrey Epstein's abuse has left some who were anxiously awaiting the files disappointed.

The documents' release was prompted by an act of Congress that directed the US Justice Department (DOJ) to make materials related to Epstein's crimes public. But some documents have numerous redactions, and others have not been shared publicly at all.

The lawmakers who pushed for these documents to see the light of day have said the release is incomplete and described the Justice Department's efforts as insincere.

Some legal experts also warned that the breadth of redaction may only fuel ongoing conspiracy theories.

But Deputy US Attorney Todd Blanche said on Friday - the day the materials were released - that the department identified more than 1,200 Epstein victims or their relatives, and withheld material that could identify them.
