"The song [Family Snapshot] is based on "An Assassins Diary", the notes and scribbles of Arthur Bremmer, who shot and crippled Governor George Wallace of Alabama in 1972.-- "Peter Gabriel: An Authorized Biography" by Spencer Bright,`It was a really nasty book, but you do get a sense of the person who is writing it.' says Gabriel, `Bremmer was obsessed with the idea of fame. He was aware of the news broadcasts all over the world and was trying to time the assassination to hit the early evening news in the States and the late night in Europe to get maximum coverage.'
Bremmer originally went after Nixon, which explains the references to the Presidential cavalcade in the song. Gabriel has dropped stage references to Kennedy's assassination having been convinced a solitary assassin was not responsible for that murder."
