It’s been 40 years since JFK’s assassination. Still the conspiracies abound. My favorite take on the subject is Libra, Don DeLillo’s novel about the life of Lee Harvery Oswald. DeLillo has also recently participated in an online Frontline forum about Kennedy’s death. DeLillo calls the assassination “vintage American violence, lonely and rootless” — the implicit question then becomes, if that’s vintage, then what’s the new form of American violence?
