The thing is, I doubt they'll make any public apology. It's pretty simple. To do so is to expose them to some serious consequences in a lawsuit. The right thing to do is to admit they were utterly, completely wrong. But, companies are run by $$$. To admit wrongdoing would be to throw away a significant chunk of money. Their lawyers are almost definitely telling them to publicly shut up about this, and keep it that way, until (at least) it is certain a lawsuit isn't going to be filed, or a lawsuit has completed.
Their postings on their facebook profile are exactly in line with that. No admittance of wrondoing, an abstract stance on their policy, and they are 'investigating'. You will NOT get anything more from them.
That, to me, is why a lawsuit is so important here. All they've done so far is to attempt damage control. They're terrified of an expanded class action lawsuit, which is why they're having their employees sign the notice (if they're telling the truth about that, and it's not just one store). This is how corporations work. Look at how Toyota handled the mass recall; did everything they could to protect their pile of cash. There's thousands of other examples. Ross will act no differently. Count on it.
There will be no public apology. There will be no public admittance of wrongdoing.
