Id agree to them spearing the copper but to be done in secure military location, then when they go towards him with the spears id whack them too, as much as i agree they are natives, id give them land and say now fook aff, let them fend on their own, then change the laws that the white man in oz can shoot to kill any native trespasser on his land, as i said before if these peoples(natives) were any good they wouldnt have been 3rd worlders
