Local LV news media sucks. They're mostly dependent these days on getting tipped-off by social media, and in the case of TV, if they can't get some sort of video or even still-image to show, they won't go with the story at all, or will tend to downplay it. Local LEA PIOs provide great info sound-bites, but local government politics (promoting an image of fun & safety) +LE Admin limits the types of press releases to where they tend to be provided only if it's a major incident that due to location or other specifics, the public is already aware of, they need the public's help, they want the public to stay-away from an area, or they're announcing they've made an arrest. A lot of crazy stuff occurs in Henderson that doesn't get covered, because the local media is too busy trying to cover the craziness in LV & NLV, though due to LV craziness, plenty of NLV craziness is also missed. On an average day's 30 min local TV 'news' program here in the Southern Nevada market, roughly 15% of it is international/national/local hard news, 15% is weather, 20% is some special-segment/feel-good/'public-interest' piece, 10% is traffic, and the remaining 40% is commercials. Sometimes, at-least local channel 8 runs the exact same special-segment/feel-good/"public interest" piece they ran 24 hours prior during the program.
When you see a local news reporter on TV out covering a story (important NEWS story, let-alone the 'special interest' stuff), in many cases, they're doing everything solo -- collecting footage, setting up their own camera shot for a live scene, etc. I remember the old days where major TV stations in each large market could afford to have a bunch of the electronic news gathering trucks & at-least one satellite news gathering truck in the fleet, and would respond to stories with the on-air talent/reporter, with the camera/sound person driving, and maybe a producer or intern riding in the truck with them. Budget cuts, competition from social media & technology has reduced that to often just one person doing all the tasks. In those old, old days, the producer/assignments person/news director would talk to the units in the field via RF, usually a repeater output in the 450-451MHz range, and it was amusing to hear the person at the station actually provide story details to the reporter out in the field, whom the public masses assumed would have gathered that info via on-scene research. Likewise, the traffic person at the station feeding the "reporter" in the station's traffic aircraft all the news.
IFBs in the 450-451MHz range can be fun to monitor just before, during & just after live reports from the field.
Anyway, usual lame 'argument' against encrypting. I love how the OP says he read a story on-line about an incident, then tries to say there was no coverage about it. But sadly, the event that inspired this post is pretty common (i.e. not extremely 'newsworthy') plus I believe there's an unwritten agreement between local gov't & PDs to be very careful promoting or releasing details of criminal incidents happening at area resort-casinos & other tourist destinations. Any scanner-geek could have easily learned about the shooting event by monitoring the appropriate Fire/EMS radio channels (non-secure).
