John F Kennedy ridiculed idea of being shot three years before his assassination

US President John F Kennedy told his Secret Service agents three years before his assassination that no one was going to shoot him and complained that his security was excessive.

Following his 1960 election, Kennedy told an aide that Secret Service security was excessive and he was not at risk of being killed, the Daily Mail reports.

"They're making me uncomfortable. Nobody is going to shoot me, so tell them to relax," he said at that time.

Kennedy was, however, gunned down in Dallas, Texas, on November 22, 1963 by Lee Harvey Oswald.

His assassination sparked off a string of conspiracy theories.

Kennedy's concerns emerged during a series of audio tapes made in the 1960s by his aide Kenneth O'Donnell and recently unearthed by O'Donnell's daughter.

According to the paper, the tapes also include an eerie premonition from Kennedy about his son, John Jr, and how his love of flying could end in disaster.
