The attempt to tackle the sexual legacy of John Kennedy was an unmitigated disaster for Sy Hersh, the low point of an otherwise illustrious career. Why would Hersh, the man obsessed with public policy, tackle this sordid tale in the way that he did?
A possible threat to national security is perhaps more understandable, but getting a prior restraint on a book for national security is near impossible; getting a book banned because people cuss or if the content is "ungodly" (look out Harry Potter books!) is a lot easier.
