I understand. I just happen to side with OP on this, from where I'm standing, it looks like a coup attempt. It doesn't look conspiratorial at all. It looks like they're saying "fair elections" but they're meaning "Republican rule".
There is no organization. There is no plan. There is no sign of a premeditated attempt to overthrow the government. There is just a mob of angry rioters barging into a government building.
I'm curious what you believe constitutes a coup.
