If there was an app that can be used to identify the DA, mayor, chief of police, congressman and senator(state and federal) of a police abuse of power incident and pester them with complaints, that would be useful. Or help people vote by sending them alerts for their area to vote out politicians that took no or little action when such an event occured. A harder challenge would be to counter-monitor police including stingrays and aerial attacks. Both offensive and defensive tools would be useful.
