Lamon's story emerged during the early 1970s in "A More Perfect Union" by Harold Hyman. Some recent writers have accepted the story as credible including Jeffrey Rogers Hummel in "Emancipating Slaves, Enslaving Free Men". For a time in the 1980s and 1990s, it was believed that a second corroborating document by Francis Lieber referred to the warrant. This was the result of a mistaken numerical citation in an earlier work. The error was discovered by John Rodehamel, a manuscripts librarian at the Huntington Library. Once informed of this error, Jeffrey Hummel described Lamon's unsupported account as "not credible." That President Lincoln considered, and then rejected, the possibility of arresting Taney is briefly mentioned in "The Civil War" produced by Ken Burns and aired on Public Broadcasting Service (PBS) public television stations.
