Not to mention that the use of spears an alien concept to them. They have unlimited resources for the taking, and they live like bums.
And how do you propose to determine who is immune? Shoot them in the chest and if they don't turn, consider that a victory?......LOL!

I suspect the introduction of Eugene the Scientist will lead the series down that trail if need be........
