Facial recognition was sold to us as a convenience. Unlock your phone. Breeze through airport security. Clock in at work without a swipe card. But what happens when the same technology moves from everyday life into war zones, and then quietly into democracies? This story traces the hidden journey of a single facial recognition company, Corsight AI, from Israel’s security ecosystem to Gaza’s checkpoints and now to the streets of the United Kingdom. Built by veterans of Israel’s intelligence apparatus, backed by Canadian capital, and battle-tested during Israel’s military operations in Gaza, this technology has been used to scan, catalogue and track Palestinians, often without their knowledge or consent. Rights groups say it has led to wrongful detentions, misidentifications and an expansion of surveillance in occupied territories. Yet the same system is now being adopted by the UK Home Office to power live facial recognition vans across Britain, even as London publicly condemns Israel’s conduct in Gaza and claims to stand for a rules-based international order. So where does the UK draw the line? Can a government condemn a war, suspend trade talks, recognise Palestinian statehood and still buy surveillance tech forged in that very conflict?
