Disputed Oswald picture is real, say researchers

It is one of the most controversial pictures in history —a backyard photo of Lee Harvey Oswald showing him holding the same type of rifle used to assassinate US president John F Kennedy.

And now a new analysis has found that the picture is authentic.

Oswald said it was fake, shortly before he himself was assassinated, and conspiracy theorists have long argued the picture was altered as part of a government plot.
