We urge designers, especially designers who seek to build a world without policing and cages, to adopt a praxis of Abolitionist Design. To do so, we have three recommendations. One, designers must refuse to design policing tools and should prohibit their work from ever being used for policing’s ends. Two, designers should resist and push back against the appropriation of design methods and discourse for policing’s ends. Three, designers must develop their knowledge and discernment of policing ideologies, and in turn, of abolitionist ones. Designers should fight to abolish literal cops and the ones in their heads. Freedom demands that, and nothing less.
