` ===Why=== The policy says, ``Self-published sources should never be used as third-party sources about living persons, even if the author is an expert, well-known professional researcher, or writer.``  Obviously, Rehnquist is not a living person, but Professor Kerr happily is, and I don't think this is a third-party source about Kerr.  So, the sentence that I just quoted is not why I removed the stuff.  The policy also says, ``self-published media, such as ... personal or group blogs ... are largely not acceptable as sources.``  And:  So, even if Kerr is an expert on Rehnquist and has written about Rehnquist in reliable sources, if the stuff was really worth reporting here it would likely have been published in a reliable source, perhaps by Kerr himself.  I hope that explains.  `
