What are we doing to make sure this never happens again in the future? Well, even before this incident, we hired a VP of HR who has implemented a sensitivity training program for all employees.
Stupid question: It's already illegal to discriminate and harass on the basis of race. Why do you need a training program to make it less risky to fire people over it?
I think it's less risky because it sends a clear signal to employees that if they're fired for being racist assholes, they don't have any real grounds for to sue for unlawful termination.
Even groundless unlawful termination lawsuits are a pain in the ass to deal with. It's better to discourage them than to litigate them.
The hiring clearly took place before the incident; whether the training took place before the incident is ambiguous. If it did, it was clearly ineffective. If not, then we have no evidence one way or the other as to its effectiveness.
There's no policy you can implement that will prevent all bad behavior. At least not until your employer goes all Minority Report on you (there's a double meaning for you).

Which was evidently ineffective.
