Lessons will be learned

An exceptionally annoying admission that someone cannot manage their job is when they say that "lessons will be learned", especially annoying when the incident that caused the comment was already a well known scenario and should not have been allowed to happen in the first place like a hacked website, lost personal data or protesters attacking the car of Prince Charles.

I know we learn from mistakes but they should really be mistakes that were hard to foresee and not stuff that has been happening for ages and which we should have learned from.

You don't let your web site be hacked and then claim that you will learn lessons when the whole world gets told to secure their computers daily after previous mishaps. You should have learned lessons from their experiences.

I'm just saying, it is really annoying.
