I don't know what specific details are being manipulated, as I'm not in the 'inner circle' ... however I can speak more generally to how I see it go year after year.
This probably won't be surprising to anyone but the purpose of news is ratings, not information. For there to be ratings there has to be something that will engage the viewer and keep them watching. As viewers, what engages us is not well thought out discussion and factual information as much as controversy and grisly details - the things that boil our blood and get our heart thumping.
An example - a few years ago I was sent a mug shot to include in an animation of a local fire chief who was killed in a traffic accident. I looked the guy up and saw that he was a true hero, leading one of the first non New York fire crews to ground zero on 9/11 to help in rescue and recovery, recieving medals for all the lives he'd saved as an Indiana firefighter while putting himself in harms way ... the kind of guy you want to honor. The story was 30 seconds on exactly how he was killed, and didn't mention any of the above things.
The vast majority of news stories are given this treatment, including the stories about the Skeltons. It makes it tought to try and put together good information because seemingly inane details are often left out in favor of who is a sex offender and who tried to kill himself and what these things could mean. To this day it's still referred to as JS's suicide attempt, when now I'm reading relatives and family members saying he had no trauma to his neck. As a reporter would this not be key information? The police keep saying they don't anticipate a positive outcome, they reiterate that point over and over again. I asked on here why they keep saying that and nobody seemed to know. These seem to be key questions.
So TS will be highlighted as a sex offender, JS will have his sordid past dug up and assumptions made that he did the worst, the FBI and Police will be blamed for not doing anything, the families will be labeled as apathetic ... so you asked what's being manipulated? I think the story is being manipulated to evoke an emotional response from us, and not for good reasons. If the point is to discern facts and put together possible alternatives to the standard narrative being portrayed in the news, we ought to avoid anything but the facts ... all the news wants to do is make you sad or make you scared so you keep watching, hoping for a better outcome than the one they've made you afraid of.
Sorry if this is too off topic
... that being said if anyone is aware of jobs for an animator outside of news media I'd be happy to hear about them
