I truly wonder how many people panicking actually bothered to understand the story and Bowman's role in all of it. He wasn't part of any active cover up, he played no role in referring Aldrich to other organizations, it isn't even clear that he was fully aware of the nature of the allegations or what happened beyond "he tried to get him into bed." His boss told him he would handle it, his boss didn't handle it, and Bowman was guilty of not following that up diligently enough. That's it.
It's really unfortunate that a lot of people simply aren't willing to stop, take a breath, and actually understand the facts before going off the deep end. Maybe the worst of it, as has been demonstrated here by a few people, that even if they learn things that they didn't know before, they dismiss them because they so fully entrenched their position that they would look silly to back track.
