I hadn't seen the uncensored version of the footage until now. Apologies if it has been previously posted.
The problem with videos like that is you only get tunnel vision not the full context. Mark Donaldson in his autobiography 'The Crossroad' mentions the dog 'Quake' who was subequently killed and his handler (though obviously not named) although not this incident. They had been warned by Int reports that a wave of suicide bombers were being prepared in Pakistan. They had already had to deal with a number of IED's
A man is spotted digging in a field by the Blackhawk helicopter crew who think this looks suspicious, who alert their passengers and land near the man. He runs off, the troops think he must have been up to know good and chase after him releasing the land shark who hurtles off and brings the guy down. The patrol catches up and the handler calls off his dog and stands over the man covering him with his weopon.
The Afghan is bricking it as he has just being savaged by a land shark and he now has an angry armed foreigner standing over him shouting in a language that he doesn.t understand. He naturely curls up in a ball (probably to prevent his goolies being bitten off by the dog if nothing else) and starts praying to allah to get him out of this as he is quite happy to wait a while for his 72 virgins. He clutches his red prayer beads.
The SASR Trooper is hyped up, thinks the mans actions suspicious as he is thinking suicide bomber or about to set off an IED and the red prayer beads are an iniater of some sort. He asks his patrol sergeant what to do, who replies either to waste him or its your call. The dog handler has a second to make a decision and decides its 'better to be safe than sorry' 'tried by twelve than carried by six' etc, and opens fire.
A tradegy of circumstances with an ordinary farmer running off when a helicopter lands near him and curls up in a ball clutching prayer beads in a natural reaction, being fatatly misinterpretated by a soldier with a different overview.
That would be my defence case if I was his barrister anyway.
