A Pokémon Go-like smartphone app called ‘Automon’ was unveiled in October 2017 as one of several new initiatives to increase the public’s contribution and engagement in police investigations in the Netherlands. Automon is designed in the form of a game that instigates participants to photograph license plates to find out if a vehicle is stolen. [---] This paper studies the example of the Automon app and contributes to the existing debate on crowdsourced surveillance and the involvement of individuals in law enforcement activities from an EU law perspective. It analyses the lawfulness of initiatives that proactively require individuals to be involved in law enforcement activities and confronts them for the first time with European Union (EU) data protection standards. It is concluded that the Automon app design does not meet the new legal standards.
