as the 48th anniversary of that tragic event in Dallas nears, a team of historians and retired Secret Service officers has used new technology to categorically confirm in their minds the judgement that Lee Harvey Oswald acted alone.

Historian and journalist Max Holland, who has investigated the 'Where were you?' moment for years, led a team which digitally enhanced a number of home videos taken on November 22, 1963.

His team studied Abraham Zapruder's famous footage as well as many other lesser-known films, and brought them all together for the first time to establish a narrative more clear than ever before...

'I'd say a main thrust of it is to break the stranglehold that the Zapruder film has on our perception of what happened,' Mr Holland told Fox News.

'In a sense, we've all been 'Zaprudered'. The film was so graphic, disturbing, mesmerising, that it became more of our perspective on the assassination than even the perspective of the assassin, which should never have happened.'

The team also discovered, in the amateur footage taken that day by Robert Hughes, a shadowy figure moving on the sixth floor of the Texas School Book Depository building - a person believed to be Oswald.
It is widely believed that Oswald shot three bullets from his rifle. One missed entirely, a second hit Kennedy and passed through Governor Connally, the third was the fatal shot to the President.

Through FBI testing it was established the gun could be fired by an experienced shooter three times within five to eight seconds.

But in Governor Connally's own words: 'There were either two or three people involved, or more, in this — or someone was shooting with an automatic rifle.'

The politician's wife believed that her husband was hit by a bullet that was separate from the two that hit Kennedy.

In the Zapruder film, the JFK's head appears to move backwards after the last, fatal shot, an indication to some that a bullet was fired from the front.

There have been witness statements that two men were seen on top of a grassy knoll to the west of the Texas School Book Depository before the shooting.

Oswald was an employee at the Texas Schoolbook Depository, which overlooked the motorcade.
