In this video they show some guy watching TV whom they identify as Bin Laden. They then show a video of OBL walking among some rocks and the narrator says that the graphic on the video says the footage was shot in 2010. To be clear, Al Jazeera isn't vouching for this date, but they do not question it.
The footage in question has been around since 2001. You will recognize it.
