Have you guys been following the GM recall fiasco? Wow - they are hanging the engineer that signed-off on that ignition switch out to dry! I can't imagine what it would feel like to have an independent investigation name a decision you made as the specific cause for 13 deaths in a public report.
Of course heads will roll, but the fact that the top echelons of their management claims they never knew about all of these safety issues is the real indicator of a company-wide culture of concealment. The people who set the tone for issue reporting are those at the top, so the people who created this issue are generally gone from the company by now with Barra and her administration in place. However, it remains to be seen whether this recent recall frenzy is just a PR move from Barra's team, or if she's genuinely trying to clean up their corporate culture.
