I think there is a balance between keeping the public informed and creating an utter shitstorm.
The Nicola Bulley case recently is a perfect example of that. The media turned it into a 'whodunnit' mystery, undermining the police and disrespecting the ongoing investigation. It almost felt like it would be a disappointment to the media if she turned out to be 'just' another missing person. They are so hungry for drama. (I guess it could be argued that some family/friends in this case involved the media a lot, but I'd never blame a family for doing this - I'd want all the awareness possible for my missing relative)
Ultimately people get invested in these incidents involving ordinary citizens, particularly like the one I have mentioned, because they can picture themselves in that situation. They want to know everything because they want to assess how 'safe' they are from something similar happening to them. But in my view, the media should have a responsibility not to sensationalise and turn these horrible situations into entertainment; the effect it has, particularly on the families of victims is despicable. I think the popularity of true crime has made this much worse, and I say that as a fan of true crime documentaries etc myself; the public feel they have a right to know as much as the police do at any given moment, and I think that is a relatively recent change.
Sorry for the long response - I feel quite strongly about this! Ultimately I think the media really need to reassess how they cover these types of events and the responsibility they hold.
