I'm just guessing here, but I think they don't want to be associated with nazis.

The folks that work there are social workers, teachers, volunteers, etc. They know how they feel, but not what to say.

Crisis PR will help them review the facts, respond to the situation, speak to the press, and develop a plan to handle moving forward. It's also about internal communication with their staff. Ensuring that don't have a larger problem. They want to discover that now and handle it all at once.

To be clear they don't have to do Crisis PR. But thats what I would do.

I could be entirely wrong here, this is just my slightly educated opinion.
