I think you need to really wrap your head around how exactly this threat or uprising might occur in order to properly appreciate the response. A lot of people get into this conversation of "well the American military would never just gun down swathes of american citizens to protect the 1%" and while true, that's entirely missing the point of how the government and their benefactors function.

If the American people decided it was time for a revolution and thought it reasonable to flex those second amendment rights, it would have to begin somewhere, 99% of the country wouldn't just drop what they're doing and take to the streets one day, particularly not in the US. So as this seed of a revolution grows, someone somewhere will eventually fuck up and get themselves some attention. Maybe someone bought too much fertilizer and was reported to local police, maybe someone made an incendiary post on the internet and got flagged by the fbi, now all members of this little coup are likely going to be at risk of surveillance through metadata analysis.

If the coup stays small and gets violent, they're looking at imprisonment as domestic terrorists, blasted in the media as radicals, and promptly forgotten about as the news cycle throws about a thousand other stories in your face. If the membership grows before things get violent, then it's very likely that eventually the surveillance may involve undercover work. If there's no attempt made at secrecy in this movement then it will be countered with classic propaganda and subversion, likely alongside censorship in the media and online as things became more severe. The group would be laughed at, or demonized, or humiliated in the media while their movements would be constantly harried by local or federal task force police.

If a large clash were to occur and the national guard were to be deployed, their mission orders would tell them that they're fighting terrorists, armored personnel carriers would roll down the street with helicopters accompanying overhead in a scene not totally alien if you live somewhere like detroit or baltimore while the nightly news would report about a "stand off with extremist radicals". At this point the collected metadata would be pursued aggressively and any known affiliated parties might be arrested for domestic terrorism, or end up in the news as a tragic casualty of a domestic gas line explosion, or perhaps find their newer model, on-star enabled car jamming on the accelerator and veering off the road.

An uprising is impossible when the 99% are only shown each other through the lens of a controlled media. Dissent can be laughed at or ignored, violence is terrorism, creating a network of radically minded people is cause for federal flagging. If the revolutionaries of 1776 tried to become active in today's America, they would be imprisoned or killed, they would be reported as terrorists, and we would forget about them tomorrow as we comment on some election news or a new show.
