A few weeks after Gray's funeral and the riot that followed, I stood on a corner in Old Goucher admiring a great, healthy tree that I had never noticed before. It bounced in the soft breeze and gave off a pleasant fragrance. Then, I walked half a block and passed a filthy couch in an alley that smelled of urine. I called 311, the city's non-emergency service line, to report the couch. Next day, the couch was gone. The day after that, there was a pile of trash in the same spot.
