For an archetypal instance of Groupthink and protection of A System, see the Penn State University Sandusky scandal

This article shows what happens to a person who tries to Do The Right Thing as opposed to the Expedient Thing. As you will read, Vicky Triponey was essentially marginalized and then expelled from her role at PSU because she dared to confront Joe Paterno about lax attitudes towards athlete malfeasance. All of the time that Triponey was fighting (and losing) battles to enforce student discipline, Jerry Sandusky's aberrant behavior was also being enabled by the same group of leaders working within the same unspoken and deeply dysfunctional set of norms.
The most interesting thing about the article is that Triponey is more sad than bitter about the events. The most appalling part of the story is not that Triponey was forced out of Penn State, but that after that happened, other schools would not employ her until after PSU's program imploded and they were forced to realize that maybe, just maybe, she might have been right all along. That sort of informal lockstep is the most appalling part of the story.
