The risk of a false positive is nonzero, but how does it balance against the value of a true-negative? Given that alternatives the police have include "picking up anyone who just looks like they might be a perpetrator" (which all too often translates to racist policing), is there value to communities (especially communities with past racial policing concerns) of tools that tell the cops it's probably not any of the people the system doesn't identify (or identifies as affirmatively not in the area of interest)?

If the perpetrator didn't have their phone on them, this is not going to help a bit. However invasive your investigative powers are, there will always remain a chance of misses. The question is how much privacy and freedom of innocents you want to sacrifice for a small further decrease of miss chance.
- fixermark 8y agoI don't mean a miss, I mean "This phone breezes through the dragnet but is clearly moving the wrong way to be associated with the crime in question, so we can discard this suspect." That'll be great news for the suspect in question if it's the black guy the cops picked up using "traditional" policing methods because he looks like he was in the wrong neighborhood.
