Regarding the specific issue of using facial recognition apps to identify criminals, and using those apps as justification for detention/arrest - has this ever been challenged in court? I know there's caselaw that supports using cameras in public, but I'm wondering about the apps that are used to "recognize", and then the decision to detain/arrest based on those apps. If I'm a lawyer challenging this, I wanna see the source code for the app; I want verification that the app is working as it's intended, the false positive/negative rate, and that there's no way for someone to "put their thumb on the scale" to get a desired outcome, etc. I'm also gonna want access to the phone that was used to take the picture(s).
