Input Junkie

Re-instituting duels, while allowing the challenging party to hire a representative would do it. But I think the unintended consequences would be excessive. Famous people's privacy was protected in the 20th century - JFK's affairs and FDR's illness come to mind as examples. But the problem today is even if you could convince the mass media to return to the status quo ante there are enough other routes for information to travel these days it wouldn't be sufficient.
