EYE

The EYE is the premier mass surveillance tool made by the United Kingdom government, the MLA, in an effort to curb crime. Atop many government buildings, EYE systems use lasers to pierce through just about anything, scanning for crimes.
The EYE system was created in collaboration with Taiwan's Kang Tao in a diplomatic bind that resulted in the influx of Hong Kong refugees that eventually brought the MLA to power. Initially an Orbital Air prototype constructed during the First Corporate War, Kang Tao's upgrades have repurposed it into an information-gathering tool with minimal effort. The process is simple: an AI mind judges everyone's actions (based on their past behaviors) and yields a majority report based on probable consequences. If the then-fugitive is a high-risk target, a PKY squad will be deployed to their location, which is constantly tracked by the EYE mechanism.
However, it has a large bypass courtesy of the MLA: the Lord's Knights are virtually unscannable, usually due to being granted preferential treatment by one of the Authority's Lords. The Metropolitan Police, PKY and foreigners do not share this benefit.
However, the streets do offer some Knights' Passes (6000eb) for exorbitant prices, if street scum can scrounge the money.
