On January 9th, the ACLU filed a Freedom of Information Act requesting info on the government's contracts with airlines, airports and other entities that use facial recognition at airports and borders. DHS, CBP, ICE and TSA did not respond, so now the ACLU is taking legal action.

"The little we do know about the government's plans for face surveillance at airports is deeply disturbing," the ACLU wrote in a blog post.

As the ACLU points out, if the use of facial recognition is normalized at the airport, the government could theoretically argue for its use elsewhere. Facial recognition still has a bias problem, and then there are concerns about data protections. With companies like Clearview AI, and now Banjo, free to operate on their own and no widespread facial recognition regulation, it's understandable that the ACLU is asking questions.
