To keep criminals from monitoring the police and getting a head start

In prior articles on this, religious nutjobs would listen to police radio and visit the active crime scene and start praying in the middle of the chaos. People and police started getting really sick of their shit during an emergency. Other flavors of morons would also show up to watch shit go down. Sometimes, private information would also get said on the radio such as names or addresses, which could lead to harassment or true crime nuts showing up to private homes.

I kinda get why making channels private for everyone but reporters (for transparency) is happening.

Imagine an active shooter situation where the shooter was carrying or had access to a police scanner and could listen in on what they knew and their movements. I don't like this idea because I think cops need more media scrutiny than less. But I do understand why it may be necessary in some scenarios.
