If I were heavily armed, and the rabble wasnt (such mobs usually are not) then the objective is to make an attempt to save the woman with or sand child. Kill a pile of the offenders quickly and the rest will run away like the feral pigs they are.
And since the world has gone to pot, I would check into the feasibility of removing the remainder of the vermin from the face of the Earth.
Shoot, I would go HK on them. :D

We need to continue working on those G's.!
