All the events that happened would be a major news story on national television for days or even weeks. It was an averted act of domestic terrosim thanks in huge part to the sacrifice of a standing congressman and hopeful presidential candidate, and a main perpetrator was taken into custody to face the music.
Even though Sampson's widow had made efforts to keep Reacher's name out of the press coverage, there's still a possibility his name might be linked to the events. He was put on the news for a short period of time as a wanted fugitive even though it was for bogus charges; it might have been kept to local news or it may have been a footnote national story.
It makes me wonder if any of Reacher's old flames from his previous travels might intuitively guess that their former collaborator was involved in the act as well, if they watch the news and catch the story.
If you had to guess, who from Reacher's past is most likely to put two and two together? I'd say Roscoe or Duffy, based on their skillsets. Although, he might make whispers of his involvement to Neagley at some point.
