Miranda is a black box-like arrest documentation device that records video, audio, motion, impact, location, and other data and streams it over cell phone data networks to third party observers such as the ACLU.
For the project to gain widespread acceptance in society, Miranda needed to address both sides of the story - considering use by police as well as protester.
Miranda in use, applied with a rugged Tyvek label. Sponsored in this case by the ACLU and distributed before a demonstration.
Police carry multiple Miranda devices, able to apply them to protesters who don't already have one. The Miranda warning that gives the project its name could be modified: "You have the right to the use of an arrest documentation device..."
The form is intentionally angular and defensive, with drafting the sides allows the part lines to be moved to the bottom of the device to further discourage tampering.
