Sheer incompetence. I hope (probably in vain) that police departments and local governments become more savvy technical evaluators of fancy tech solutions.

There was a huge fracas re: ShotSpotter in my town, where both the municipality's CIO and auditor (+ their internal research capacity) were sidelined. It took a sad amount of handholding elected officials through ShotSpotter's technical claims for them to shelve a planned deployment.

It’s not incompetence. This is simply not caring. If they had any interest in fixing this they would have. It just wasn’t at all important to them.
