Enable "Pedestrian War" cheat it will cause all civilians (except ones that sit down or are made to flee) fight everyone and everything. So far they have a arsenal of weapons and melee on my patch, but I can't figure out how to fix rifle animation bug looks. You can add weapons to civilians (one handed firearm/melee only and no special so far the animation is bad) by changing it in spawn_info_ranks.xtbl. In Saints Row III and IV because of Professor Genki (special civilian spawn) civilians gain the ability animation to use shotguns, rifles, launchers and more. That is not the case in Saints Row 2, add SMG, Pistol, melee weapons to civilians only.
