If you could take a cross-section of the average city block, you would see the ways that the built environment of surveillance—its physical presence in, over, and under our cities—makes the various types of surveillance an entwined problem that must be combatted through entwined solutions. We decided to create a graphic to show how—from overhead to underground—these technologies and legal authorities overlap, how they disproportionately impact the lives of marginalized communities, and the tools we have at our disposal to halt or mitigate their harms.
