Incredible, if not entirely unanticipated, scenes! In response to some of your questions I have the following thoughts offered as a non-expert on US politics:
The invasion of the US Capitol doesn't seem to have been a coup, which would imply organisation and coordination of a higher standard than was on display. If disruption is the zeitgeist, then this was a disruptive event rather than an insurrection, which implies a sustained, and usually armed, uprising.
The network keeps me up to date in the field.
