I don't really see how this interpretation of what you wrote makes sense. "Also there seemed to be no substantive discussion prior this about the police using Rekognition until it became a hot button issue." If you didn't mean that it wasn't an issue that was high in public awareness or concern wouldn't it be tautological that it wasn't high in public awareness or concern until it was a hot button issue? Like, the definition of it becoming a hot button issue is that it's high in public awareness or concern. Am I misinterpreting something? Did you mean something else and I just got it wrong?
