I woke up the next morning and Fox News was reporting that unknown suspects had vandalized City Hall. I went back to the entrance and handed the guard my driver’s license and a letter explaining what I’d done. Several police officers were speaking in hushed tones near the gates, which had been washed clean. I was expecting them to recognize me from eyewitness descriptions and the still shots taken from the surveillance cameras and immediately take me into custody. Instead, the guard politely handed me back my license, explained that I didn’t have an appointment, and turned me away.
