Now, imagine you’re a parent, and in the middle of your neighborhood, there is a playground. Of course you’d want that playground to be a joyful, creative space. If your neighborhood were a crowded public housing development in the middle of a city, the chance to bring your children to a small outdoor sanctuary where they could stretch their bodies and imaginations would be even more precious. You might hope the jungle gym would include a pretend steering wheel, storefront, or spaceship, like the equipment in thousands of playgrounds across the country. Imagine, then, if instead the “sanctuary” the city provided for your children featured a pretend jail.
