Ever notice how cops tend not to fuck with armed protesters?
People carry a gun to protect themselves and their family. Not necessarily random strangers. In fact, most state CCW classes tell you to stay away from situations where you might have to use your gun to help others.
The good guy with the gun is either a cop, or a concealed carrier in the middle of the situation. In this case, cops were the bad guys.
For combat MOSs, they should all be expected to pass the same physical fitness standard. You either raise the female standard to the same level as males, and have fit females. Or you can lower male standards and have less fit male and female service members in combat. Or you can meet somewhere in the middle and still have less fit male and female service members in combat. Personally, I say raise the female standard for combat MOSs to that of males.
Combat is not about equality. It is about lethality and that is it.
