I'm sorry, but for me when I read something this horrific nothing works better than a little sarcasm / humor.
I think the points (yes I think sarcasm can be a valid channel through which to voice your concerns) I'm trying to make here are:
1) People making decisions for corporations as large as GlaxoSmithKline tend to be disconnected from the impact of their decisions.
2) There are only 2 reasons something like this can happen. (a) Malice, or (b) incompetence. I reluctantly choose 'b'.
3) In general it's the people who actually make the mistake who get fired, and not the incompetence in the board room that creates the environment where these kinds of mistakes can actually be made.
As a side-note, I live in midwest in U.S. and am not a reporter or involved in media, so I'm pretty ill-equipped to go seeking out facts which I'm sure even a skilled reporter will have a difficult time trying to uncover.
