THIS THIS AND SO MUCH THIS.
Not to mention that there is also the issue of the fact that there would be a very great potential for some parts of the military to refuse to take action, and go against the government themselves, and they probably wouldnt want help from the public in their coup attempt, as it means people untrained in military tactics (and more people to deal with if they succeed in taking power).
The law was not written with the existance of weapons that cost more than the net worth of multiple families in mind. It was written back when it was plausible that a private militia could round up enough strength to take on the goverment military.
hell, even by the US civil war (which is a misnomer, as it was actualy an unsuccessful war of independance) it took the armies loyal to the south to put up a fight.
So yeah, any as the guy above me said, any government opressive enough that people would actualy try to stand up against it (well, more than isolationist, racial supremicist types), said government would probably not see anything wrong with using the army against its own people. (and seeing as how you have had many points in your recent history when the military has been called in to deal with protests, this should be quite obvious that there are people who would be more than willing to use the military against civilians)
