The fight isn't whether or not ICE should have facial recognition software. The fight is to make ICE act in accordance with our values. Some agency (ICE or whatever replaces it) will still need to protect the borders, and that protection will require facial recognition software.
If you hate ICE, you should also probably hate defense contractors more, because they have very little moral qualms about accepting contracts from the government, even ones that may violate human rights. And that's where that money is going to go now.
