Most Americans think John F. Kennedy slain in conspiracy, poll finds

A clear majority of Americans still suspect there was a conspiracy behind President John F. Kennedy's assassination, but the percentage who believe Lee Harvey Oswald acted alone is at its highest level since the mid-1960s, according to a new Associated Press-GfK poll.

Cheryl Casati, 62, who retired from the Air Force after 20 years, watched it all unfold on television back in November 1963. She said she's “extremely sure” there was a conspiracy. The killing of Oswald, the accused shooter, just days after the assassination is part of the reason why.

“There's too many holes in explanations,” the Phoenix-area woman said. “That just could not have happened easily in that time and place. And (Jack) Ruby shooting (Oswald) could not have happened as easily as it did.”

According to the AP-GfK survey, conducted in mid-April, 59 percent of Americans think multiple people were involved in a conspiracy to kill the president, while 24 percent think Oswald acted alone, and 16 percent are unsure.

A 2003 Gallup poll found that 75 percent of Americans believed there was a conspiracy.
