This past week, Americans watched as the hallowed chambers of the Capitol were overrun and defiled, not by some foreign enemy of democracy but a mob of their fellow citizens. And then they tried to make sense of it. In letters to the editor and posts on social media, they raised their voices. In Iowa, a lifelong Republican mourned the shredding of the country’s political norms. In Tennessee, a pastor and activist wondered if the rioters’ behavior might bring change. In Mississippi, a young teacher worried what her students will make of the violence. Days later, their anger, fear and uncertainties still linger.
