There was a fire near the Capitol on Monday. The smoke came from inside Washington’s “Green Zone,” or the especially secure area patrolled by the National Guard, put in place to ensure that Wednesday’s inauguration does not face the same violence as Congress saw with vote certification on January 6.

With the fire in the Green Zone came a brief panic. Did the dark clouds herald a second assault on the Capitol in as many weeks? To the relief of breathless news anchors, in a panic about fears of bombs and gunmen, the fire had a far more mundane explanation. A homeless woman, trying to keep warm in winter, was using a portable heater. Its fires spread, consuming her possessions and burning her, but she declined a trip to the hospital.
