The 'innocent farmers' in the shot who are 'farming' at night because 'it's cooler', were actually moving weapons and ammo for use at a later date against British and American forces. A subsequent visit to the scene revealed that the men had been armed, there were weapons in the truck on the right, and that the man furthest to the left does not run to get his 'hoe' out of a bag (because he's just there doing some farming while it’s cool), but is actually pulling out an RPG.
As for the guy on the right, it was his choice to be there. Had he lived (and the video shows no evidence that he did not), there's a good chance he'd be out there now plotting and executing operations against British or American military and civilian personnel.
