Their target would have to be the Talking Heads and their management.
The Talking Heads push the narrative as dictated by the station managers.
No one will then want to take on a broadcasting job/career if it meant risking life.
Station managers disappearing would have a effect on the morale of the subornate Talking Heads.
Lone Wolves would then seek various Pols and public figures as opportunity present.
There would be no communication other than news reports of someone being "gone". No logistics needed to support a army or a squad.
Each Lone Wolf goes back to his daily life, with out attachment to any organization.
Reminds me that I wanted to reread Unintended Consequences.
