Security through obscurity is never a good strategy. If the public starts listening it is good.
If the services that stream online there are other ways to monitor those frequencies such as rtl-sdr [realtek software defined radio] that folks will start to use to monitor this.

Listening to police radio should be as available, recorded, and easy as bodycamera footage should be.
It will never be until we actually start to monitor and complain when it is made unavailable.
