Imagine a room with a hundred monkeys. Each monkey is pounding on a typewriter. One of these monkeys (we'll call him monkey A) through this random act of pounding, writes the Starr report in all of it's ignominy (including Monica and Clinton's most lurid acts). Since we all know that monkeys cannot read and certainly have not heard of the Starr report, Monkey A has a valid common law copyright on the Starr report since Monkey A created the Starr report itself. That monkey can file for a Registered copyright, which it will get. Once Monkey A has filed for that report, within the required 5 years to file, there will be a presumption that it created the Starr report and the burden will be on anyone else who has not filed (including Kenneth Starr) to prove that he actually is the creator. Interestingly, in the case at hand, both Monkey A and Starr would have concurrent rights.
Filing for a Registered copyright also gives the owner of the copyright statutory damages against all infringers (treble damages). A copyright filed today will last the creator's lifetime plus fifty years.
