There was an article in recent months about the loss of communal spaces for adolescents. Put a group of teenagers in a park just hanging out, and a suspicious local will dob them in as loitering. Play a noisy game of football and someone reports it. Other places are pay-to-play. Or have alcohol and designed for adults.

This isn't the one I was thinking about, but is on the same topic: https://www.jstor.org/stable/43323577
