One of the homes flying an inverted flag during that time was the residence of Supreme Court Justice Samuel A. Alito Jr., in Alexandria, Va., according to photographs and interviews with neighbors.
The upside-down flag was aloft on Jan. 17, 2021, the images showed. President Donald J. Trump’s supporters, including some brandishing the same symbol, had rioted at the Capitol a little over a week before. Mr. Biden’s inauguration was three days away. Alarmed neighbors snapped photographs, some of which were recently obtained by The New York Times. Word of the flag filtered back to the court, people who worked there said in interviews.
