Don’t need to imagine too much, plenty of current examples (Fance, HK, Venezuela…etc.) All political/.gov based sparks that morph into something else from where it started. Tuning into fight for various freedoms, real or perceived, seem to be the common theme.
Right now the US has plenty of politicians at all levels, on all sides willing to throw fuel on X fire by design or otherwise. Just a matter of time now, point of no return isn’t even in the rear view anymore.
Currently if .gov gets earnest about clamping down on anything 2A, rest assured .gov PTB will know what’s to follow and have a plan(s)….not good for the commoner. Will probably start with admin/bureaucratic repercussions, EG; want health care, tax benefit, food, whatever X benefit then turn in/register you arms. MSM only too happy to help and plebes willingly fall in line. Then…the mouth of truth,,,neighbor against neighbor. Door to door is highly unlikely.
Guaranteed some .gov muckity mucks have played out a “siege” addressed by Namelus. Add in natural disaster, wrestles natives, broad definition of “terrorist”, national security, etc. as a catalyst and there’s the easy button under the guise of “I’m with .gov and here to HELP”.
