November 22, 1963 — U.S. President John F Kennedy is assassinated

One of the defining events of its era, the assassination of President Kennedy remains a remarkably controversial one, even today. Conspiracy theories abound as to who shot Kennedy and why.

While the official story, that Lee Harvey Oswald did it, with the rifle, in the book depository, is plausible, it is also notably incomplete – there are any number of holes and anomalies in it. The murder of Oswald only two days later, before he could stand trial, has done nothing to quell these uncertainties.

On a symbolic level, the death of Kennedy was the end of an era in many ways. Quite aside from the idealism that he brought to the nation, his death marked a change in the way America saw itself – no longer the lily-white paladin, but more the grim avenger willing do the dirty work no one else would – although in fairness, this change of self-image would take the rest of the decade to be complete.

April 15, 1974 — Patty Hearst participates in an SLA bank robbery

Patricia Hearst was 19 years old in 1974, when she was kidnapped from her apartment by the Symbionese Liberation Army. Heir to the Hearst family’s millions, she was originally kidnapped for the ransom money, but soon became a victim of Stockholm Syndrome. On April 3, she announced that she had joined the SLA, adopting the name Tania.

Two weeks later, on April 15, she participated in a bank robbery alongside other members of the Army, and a warrant for her arrest was issued. She was arrested in September, tried and sentenced to 35 years imprisonment, although her sentence was commuted to time served (in this case, 22 months). Later on, Hearst was pardoned of all crimes, and became an occasional actress.
