I mean... Let's just take your example of "we have a jumper at x and y street". Is it really a good idea to have everyone know that? Do we want "journalists" to drive over their and take pictures of people in crisis (possibly worsening it).

Or let's imagine a car chase, do we really want criminals to know that a spikestrip is set up 2 streets ahead?

Do we want information like warrant and licence checks to be held over unencrypted radio transmitions. Allowing everyone who wants to to listen in and learn about people's criminal histories?

Just to add, I am aware that the whole idea of privacy isn't really a thing in the US, the names and mugshots of arrested people are literally made public in some (all?) states, so you probably don't care about the last point, but the rest still stand, and in lots of countries everyone's privacy is considered a right, including that of (suspected) criminals.
