Ronnie’s case has evidently garnered significant public interest. This particular letter is a good example of how one part of the public views the case: as the defense of a powerless boy against the might and authority of the State/the Crown. Without getting too technical, the U.K. state has political power but is ultimately constitutionally ruled by the monarchy (the Crown). That’s why Ronnie’s case is presented as being against the government
and the Crown; they’re essentially interchangeable for the purpose of the play.
