@Ohh-Rah, I hear ya. It's like Emily Ratajkowski (look her up if you don't know

) walking down the street naked; people are gonna look (I'm gonna look). If the broadcast is available, people will listen. It's human nature.
Specific addresses, phone numbers, movements, descriptions, etc. were broadcast. I know a few tried to circumvent with cell phone use but is that really how it should work? Several cell numbers were actually broadcast over the air. What if it were a major incident (ie 9/11) and cell use was not available? That's not a good process.
A few challenges I've heard cited in re: to encryted comms are:
1. Cost: obviously encryption comes at a higher cost - but these days is it really that much higher?
2. Increased complexity/potential issues with inter-agency communications: Does agency X have the same keys as agency Y, sometimes even communicating between agencies in the clear can get muddied, ex. LEO may not broadcast on the same freq as another agency, even in the clear.
3. Transparency: this is a weak argument as I'm not aware of any requirement for comms to be available this way, although I suppose some cities may have a requirement, especially days. Certain types, particularly media, may cry foul on this one.
However, I don't see these as signifant barriers to tightening up the release of info (#2 is probably the most legit of any of them). It really should be addressed. There is a right time for information to be made available and it's not while things are still unfolding.
