It's an interesting business to be in these days...
My City Encrypts 100% communications including EMS, Fire, Police and Emergency repose, it is a stupid policy but...

Few things there, first "victim of a crime", most area's criminal reports are public records as they should be. Allowing the police to operate in secret is a very bad thing
Further outside of location information is a rare that other personal info is transmitted over the air anyway, general descriptions etc sure but...
Finally I think the public value, and transparency we get from having open air dispatch far far far far outweighs the limited privacy concerns. People say the same things when police are mandated to wear body cams, just like in those situations the public right to know what the police are actually doing far outweighs some minor privacy concerns.
We need FULL transparency in policing right now.
