This sounds like 1970s' movies depicting groups of teenage and younger kids roaming the streets throughout the night after all the community centers, arcades, and malls [i.e. any communal source of entertainment] closed. Midnight skateboarding in abandoned lots, drunk 11-year-olds, graffiti, sneaking out the window as a matter of course ... parents having no idea where their children go at night [remember "Do you know where your children are?"? Forgive a "wrong decade" but the point stands] ...

Of course this is all "crazed cinema depicting crazed societal horror", but are we truly expecting a return to such times and activities?
