In crisis communications the question of if a company or organisation should apologise is often a source of tension and disagreement. Often senior people don't want to apologise simply because it goes against their grain and isn't how they think or behave.
It's often thought that lawyers are the main barrier to offering a genuine apology. In my experience, that's often not actually the case. A good lawyer who understands reputation and media will often offer the same counsel as a public relations professional with crisis communications expertise. More often the problem is the lawyer providing the advice isn't a reputation or media expert, but is a generalist or commercial lawyer. They react conservatively and provide advice that is just one legal interpretation and is wrong one in the circumstances.
This is a great article by Mischon de Reya partner Emma Woolcott, who actually is an expert and explains how good lawyers and good PR people can work together on crisis communications.
She also reveals who the real villains are (although she doesn't call them villains!). It's the insurance companies who deliberately prevent directors and companies from behaving in a moral or ethical way.
