> Are you implying you will make someone liable for doing nothing wrong?
This leaves out an important part of liability and the concept of trust as a whole - neglect. Simply doing nothing wrong is not the end-all be-all. If you did nothing wrong, it's possible you should have been aware of potential things that could have gone wrong, and prevented them.
If the company and procedures are such that illegal things can happen in tandem that's something that should have been caught, and prevented. This is why we have, for example, licensing for engineers.
A civil engineer does not only need to consider his part, his bridge. He must consider the conditions, the inspectors, the wind, the future. He may be wrong, and of course we require some slack. But still, that expectation is there.
If, hypothetically and arbitrarily, a CEO claims to not be responsible for some company's evil action, I can turn around and argue that by being CEO it is his job to assume that responsibility, and that his apparent ignorance of the situation is not a defense, but rather proof of his own neglectful conduct.
