The lawyers defending Dan White in the trial for the 1978 murders of San Francisco Mayor George Moscone and Supervisor Harvey Milk said too much sugar, among other things, influenced their client to commit homicide. White, the defense said, had been depressed at the time of the murders. And he had recently started to eat junk food. White's lawyers cited the potential for poor eating habits to intensify mood swings. The use of this evidence gave rise to the term "Twinky defense."
