I think that this is a leak of a particular right-wing group, not leaks of left-wing groups? What incident are you referring to where part of the US was occupied with automatic weapons? The closest thing I can think of is the Seattle CHOP/CHAZ/whatever the heck it's called. But AFAIK people there were only open carrying semi-automatic weapons, not fully automatic ones.
