The London Method and the Swiss Privacy Panic

The Metropolitan Police in London have discovered a rather efficient way to clear their backlog of suspects: automated facial recognition in public spaces. Authorities report excellent results, having apprehended 2,500 individuals since 2024 by matching faces in real time. Predictably, this pragmatic approach to law enforcement has triggered profound alarm in Switzerland, a country whose well-educated populace prefers its security measures to be as discreet and non-confrontational as possible.

For Rahel Estermann, a Green Party politician and co-director of the advocacy group Digitale Gesellschaft, the British model represents a dystopian horror. She describes biometric facial recognition systems as a nightmare for a free society, arguing that they subject the public to mass surveillance without specific cause. Her central grievance is mathematical: she estimates that the vast majority of those scanned have committed no crime, effectively placing the entire population under general suspicion.

Switzerland, naturally, considers itself above such heavy-handed tactics. The national legal framework is notably stricter, and several Swiss cities have explicitly banned automated facial recognition outright. However, the reality of this wealthy, well-functioning state system often involves a certain polite hypocrisy. Despite the grand declarations against mass surveillance, a legal grey area flourishes at the cantonal level. Police forces in Aargau, Neuchâtel, St. Gallen, and Vaud are already extracting faces from surveillance footage to run one-to-many matches against existing databases.

Privacy advocates concede that this practice is occurring with virtually no transparency. The origins of the reference photos remain a mystery, and authorities may well be pulling images from social media platforms to identify suspects. It is a classic Swiss compromise: avoiding the aggressive optics of London's live public cameras while quietly allowing local police to conduct retrospective facial matching with minimal oversight.

The Digitale Gesellschaft is now demanding a complete ban on live biometric scanning in public spaces. Estermann warns of a chilling effect, suggesting that the mere fear of being observed undermines self-realization and democratic participation. Yet, the proposed ban comes with a characteristically timid caveat. The organization is willing to tolerate facial recognition at airports for passport checks, provided individuals explicitly consent and are offered an alternative method to verify their identity. It seems even the most ardent defenders of civil liberties recognize that modern security requires some concessions, provided they are implemented with sufficient bureaucratic politeness.
