Adam Gopnik writes one of the seventy million articles we'll see to denote the 50th anniversary of the Kennedy Assassination. I'll write my own remembrances and thoughts before the month is out but I'll say this here: In court parlance, I believe "beyond a reasonable doubt" that Lee Harvey Oswald was the lone assassin on 11/22/63. I also don't believe it's possible to change anyone's mind on this topic.
