I mean they will be punished, not by Trump, but by the establishment in general (in the grand scheme)... Those people are in politics, where your career is based on who you know, recommendations, etc. If their identities are revealed, their careers in that line of work are basically done... Testifying against your boss/coworkers probably isn't something your next boss/coworkers would look favorably upon; your name would be tarnished, blacklisted, etc. Even if you did the right thing.
Fringe leftists don't care, though, and want the full un-redacted report released publicly... They not only don't give a shit if those people's careers are ruined, some are actually
celebrating it over on various other social media ("Lololol those Trump stooges are going to get their comeuppance! They deserve it!" kind of stupidity)... Little do these idiot fringe leftists realize, however, is that their legitimately retarded sentiment is going to help Trump and other bad people in the future. Because future would-be whistleblowers/people who would testify in the case of wrongdoing will look at this episode and see these people being thrown under the bus and having their lives ruined for doing the right thing, and say 'fuck that', instead opting to keep their mouths shut.
