I don't think this will work on a channel like NewsNation. I think there are plenty of Nexstar stations that have locally produced shows with segments like that (i.e., "pay for play" segments). But then again, what other group doesn't have stations with local shows like that?
In NewsNation's case, I think it depends on the crime itself and who is involved (although I don't think they would amplify it to Today or GMA level). When NewsNation does a story like that which takes up a few minutes of airtime, they usually call on a reporter from the Nexstar station in the market where the crime occurred. If it was a really big story, then they usually call on people like Tom Negovan, Nancy Loo, or Markie Martin to cover it, depending on the region where this occurs.......
If you go to newsnationnow.com, they do have at least one or two local crime stories worth highlighting (that depends on the day and time when you're at the site, and what the crime is, of course).......
