My guess is a court would find "suspicion" unwarranted without reason for it. As the military hasn't cited any reason for the killing of the civilians in the van (no daily intel briefing warning of white vans was revealed in defense of the military), it would seem that there isn't one. Obviously civilians can be killed if there is a rational reason for it (i.e. aggression), but it's fairly certain that killing civilians without reason is not legal under international law otherwise death squads would be considerably more popular.
