War veteran Ben Roberts-Smith allegedly kicked an unarmed and handcuffed Afghan prisoner, "catapulting" him over a cliff, before telling his squadmates a "story" to cover up the execution.
But the witness who made this allegation in the Federal Court may not be forced to give evidence about an alleged murder he perpetrated for fear of criminal prosecution.
The former SAS sergeant, codenamed Person Four, told the court on Monday about a controversial mission during which local man Ali Jan was allegedly handcuffed and kicked off a "steep slope" in the village of Darwan, Uruzgan province in September 2012.
