Supporters argue that facial recognition technology helps prevent crime and enhances public safety by identifying suspects quickly and efficiently.

The risk lies in the potential misuse of data and erosion of civil liberties as surveillance becomes more pervasive.

Private companies involved in developing and selling facial recognition software may have a vested interest in expanding its use, regardless of privacy concerns.

The UK's decision to allow live facial recognition could lead to broader adoption across other cities and countries, potentially normalizing mass surveillance globally.

Public backlash against the use of facial recognition technology will likely intensify, leading to increased scrutiny and potential regulation to balance security with privacy rights.
