1981: Hinckley Pleads Not Guilty to Shooting President Reagan
In March 1981, John Hinckley Jr. fired six shots at President Ronald Reagan outside a Washington D.C. hotel, wounding Reagan and three others. The attack was later revealed to be motivated by an obsession with actress Jodie Foster.
On 28 August 1981, Hinckley entered a plea of not guilty to charges of attempted assassination. He was ultimately found not guilty by reason of insanity in 1982 and was committed to St. Elizabeths Hospital, a psychiatric facility in Washington D.C.
