They're rare and they often target famous people.
NG just happened to be the mother of SG. I really don't think SG's mother is famous. Heck, SG is famous but isn't that famous. Yes, journalists are under attack these days, but not like this and SG is pretty much neutral. There are plenty who aren't neutral and they are either loved or hated. But I see SG as neutral. (It's probably part of the NBC ethics since NBC is not cable and subject to FCC restrictions, cable is not) Some journalists aren't even registered to vote.
Anyway, even if a journalist is hated, well they did do a job on Charlie Kirk. He was sort of a journalist. Still, he wasn't kidnapped for ranson. He was brutally murdered by someone who became angry over his influence. (Rage was the motive, not money)
Rich and famous would be someone like Brad Pitt or the head of a huge company or something. I remember when that stalker killed the actress from my Sister Sam. (Money wasn't the motive) I just don't see journalists as "Rich". Yes. well off, but just not rich enough to go through all this trouble.
