My grandmother just got arrested in Berlin with my kids what do I do now?

She's in jail for hate speech and glorifying Nazis. She is senile and thinks she's back in the third reich, so she was babysitting today and she drove my kids to Berlin to meet Hitler. She was doing the Nazi salute on the parking lot where Hitler's bunker used to be and getting my kids to do it too which created a scene. Do you think my kids are scared? What should I do about this?
