A mob occupying private land, for weeks (months?), and declaring autonomy under a radical, explicitly and overtly anti-american, revolutionary flag, threatening and ejecting any approaching officials, including medical services, with violence. Particularly when this mob is affiliated with a decentralized network throughout the united states with similar goals.
Storming the capitol with weapons, having leaders with knowledge of the layout, and actually spilling blood. The picture of the right in this country by media is generally a caricature of an inbred, uneducated southern hick, so it's easy to pretend that they planned for a serious coup and we're just completely incompetent. But the lack of weapons in any significant quantity, or their use, or even their brandishing in the capitol, suggests that there were never any serious plans for a coup or even for violence.
The fact that "insurrectionists" came within 5 feet of the entrance to the chamber with the politicians they were allegedly targetting and obliviously walked past it more likely shows that there was no serious preparation, given that the layout is easily searchable online.
This is manufactured hysteria by the media, for political goals. It comes from the same place as this twitch policy - we are in the midst of a dirty culture war.
