If Bowman had followed up to make sure something was being done and was told that the actions taken by HR (actions is a strong word to use in this case) were confidential, I could almost, almost, give him the benefit of the doubt. I've read nothing about that happening. The only person who seems to have followed up was Jim Gary, who followed up with Bowman and was assured it was being handled. A person with any sense of morality would have followed up, and, if they caught wind of the "participate in an investigation or resign" offer made to Aldrich, would have gone to the media, resigned, or both.
Bowman had nothing to lose by taking a principled stand. He would have surely been hired elsewhere if he decided to resign. If he had pressed the issue within the organization, chances are good that his clout would have been enough to force an investigation, particularly if he threatened to go public about the team's half-assed handling of serious criminal allegations.
He didn't do anything, though. He was more than happy to wash his hands of it and expected nothing to come back on him. He is sorry because he was caught in the act of doing nothing and had to leave the NHL for a little while. His selfishness is apparent. His tears are crocodile tears.
Yeah hindsight is 20/20 and all that, but that's why anyone of character tries to do the obvious right thing instead of passing the buck.
And if Q actually did say something about not letting this distract from their Cup run it just makes everything that much worse.
