Joseph R. McGinniss, Sr. (December 9, 1942 – March 10, 2014), known as Joe McGinniss, was an American non-fiction writer and novelist.
 The author of twelve books, he first came to prominence with the best-selling "The Selling of the President 1968" which described the marketing of then-presidential candidate Richard Nixon.
 He is popularly known for his trilogy of bestselling true crime books — "Fatal Vision", "Blind Faith" and "Cruel Doubt" — which were adapted into TV miniseries in the 1980s and 90s.
 His last book was "The Rogue: Searching for the Real Sarah Palin", an account of Sarah Palin, the former governor of Alaska who was the 2008 Republican vice-presidential nominee.
The controversy over Fatal Vision, journalist and author Joe McGinniss's best-selling 1983 true crime book, is a decades-long dispute spanning several court cases and discussed in several other published works.
Jean Lanfray (1873/74 – February 26, 1906), a laborer who was French by birth but living in Switzerland was convicted of murdering his pregnant wife and two children in a drunken rage on the afternoon of August 28, 1905, in Commugny, Switzerland.
 It was later revealed by police that he had drunk an excessive amount of wine and hard liquors that morning, along with two ounces of absinthe.
 However, due to the moral panic against absinthe in Europe at that time, his murders were blamed solely on the influence of absinthe, leading to a petition to ban absinthe in Switzerland shortly after the murders.
 The petition received 82,000 signatures and absinthe was banned in Vaud shortly thereafter.
 A 1908 constitutional referendum led to absinthe being banned in all of Switzerland, and absinthe was banned in most European countries (and the United States) before the outbreak of World War I.
