We are very reliable as get our data from the Member created inmate profiles and the public information postings on government websites. Very few of them post the release date and offer it when it's a public record. The Department of Corrections or Bureau of Prisons keeps a record of those. some have the release dates and others don't. Sometimes you have to dig further by contacting the Clerk of the Court or US District Court to get the actual sentencing and commitment order, and then follow that trail.
