US governments are already beginning to use the technology in a limited capacity. Last week the New York department of motor vehicles announced that it had made more than 4,000 arrests using facial recognition technology. Instead of scanning police footage, the software is used to compare new drivers’ license application photos to images already in the database, making it tougher for fraudsters to steal someone’s identity.

without proper rules, deploying police body cameras en masse threatens to create a pervasive surveillance tool and turn what is supposed to be a check on police into a worrisome increase in police power ... in order to avoid missing events that should be recorded, it’s best to offer clean-cut rules rather than looser, discretion-based standards, and to have clear and strict policies that cameras should be on whenever officers are interacting with the public or engaged in a police action.

The new rules significantly relax longstanding limits on what the N.S.A. may do with the information gathered by its most powerful surveillance operations, which are largely unregulated by American wiretapping laws. These include collecting satellite transmissions, phone calls and emails that cross network switches abroad, and messages between people abroad that cross domestic network switches. The change means that far more officials will be searching through raw data.

The US, along with any sufficiently-connected country, is now only a few court directives, or a state-sponsored hack, away from an active surveillance state... The deportation force envisioned by Trump, targeted with court-released Facebook data, is a legal possibility ... Searches, emails, messages, transactions, browsing history, and millions of other data points the tech giants store can pinpoint millions of American’s identities with unrivaled precision.

the very systems that enable immersive experiences are already establishing new forms of shockingly intimate surveillance. Once they are in place, researchers warn, the psychological aspects of digital embodiment — combined with the troves of data that consumer VR products can freely mine from our bodies, like head movements and facial expressions — will give corporations and governments unprecedented insight and power over our emotions and physical behavior.

police have been testing an aerial surveillance system adapted from the surge in Iraq. And they neglected to tell the public ... the Baltimore Police Department had been using the plane to investigate all sorts of crimes, from property thefts to shootings. The Cessna sometimes flew above the city for as many as 10 hours a day, and the public had no idea it was there ... Almost everything about the surveillance program feels hush-hush; the city hasn’t yet acknowledged its existence,

The Blackwater of surveillance, the Hacking Team is among the world’s few dozen private contractors feeding a clandestine, multibillion-dollar industry that arms the world’s law enforcement and intelligence agencies with spyware. Comprised of around 40 engineers and salespeople who peddle its goods to more than 40 nations, the Hacking Team epitomizes...the “era of digital mercenaries.” ... a worrying trend: corrupt regimes using surveillance companies’ wares for anti-democratic purposes.

Aside from a 2013 law that established a way for parents and juveniles to challenge a child’s inclusion in the database, most people can’t find out whether they are in CalGang. An effort to create a similar process for adults failed last year amid heavy lobbying by law enforcement agencies, which use the data to build files and bring charges against people based on their alleged gang ties ... CalGang has created, in effect, a statewide investigative file blocked from external scrutiny.

open borders are an immutable fact of Europe. It is the failure to coordinate across divides that is the real problem. Long before the refugee crisis...police and other officials responsible for tracking terrorists had already complained that the absence of routine information sharing or a Europe-wide registry of suspected radicals made their job impossible ... The United Kingdom and Scandinavian countries harbor deep distrust about how some member states will use such registries.

In a world without cash, every payment you make will be traceable. Do you want governments (which are not always benevolent), banks or payment processors to have potential access to that information? The power this would hand them is enormous and the potential scope for Orwellian levels of surveillance is terrifying.
