I had this app installed for a short time. I removed it when it said "shots fired" on an affluent block nearby. It was teenagers playing with firecrackers. As happens in the neighborhood quite regularly.

I couldn't believe it. Uninstalled immediately.

That was years before the "tough on crime" rhetoric/scare/moral panic that's only amplified since then.

Edit: people are replying that the data source is 911 calls, as if that leaves them off the hook. Maybe this is evidence that 911 calls should not be sent unfiltered as push notifications. That is on Citizen.
