Identify persons of interest to law enforcement through facial recognition

Identification of "persons of interest" for law enforcement to intercept or track through facial recognition is a high profile use case for AI. Inevitably the debate about the trade-off between individual liberty and security effectiveness plays out differently according to local political expectations. In addition, actual levels of accuracy are a concern both in terms of effective implementation but also civil liberties (algorithmic bias is especially concerning on different ethnic faces for example). In some countries such as China emphasising the supposed effectiveness of the algorithms is a key part of national security communications strategy.
