While stories like these are great exposure for radioreference.com, the community service provided is minimal as few people are willing to set up their living rooms as "command centers" and live in fear as this couple has. So I am not sure what the wide spread benefit is to a community. TV and AM/FM radio already provide public service announcements in situations like this and police radio has never been effective at this (except maybe in tiny towns where everyone has a scanner) as most people don't listen to scanners. What stories like these do is make public safety aware that their radio traffic is not secure and usually results in more discretion given to what is said over the radio, more landline exchange of information and other means to not allow you to hear what is going on.
Very true. But I have not said anything about people with scanners helping the police.
We are talking about the already questionable practice of streaming LE radio traffic as if it were a means to alert a community of dangers in the area.
