Since then, Deputy Police Chief Rick Martinez and other Santa Cruz police leaders have visited other cities to explain how the app works.
Some law enforcement agencies have balked at providing the police scanner on mobile phones. They feared it could aid criminals.
Martinez pointed out that the scanner already is publicly accessible on radios. Also, police have the option to transfer important radio traffic to a secondary channel or make it private.
“Generally it's pretty inane to have (mobile phone access) on your primary channel,” Martinez said.
