Ignore the threats. From the video on the youtube site:

"This video is backed by a community of concerned citizens including teachers, attorneys, mothers, students, and friends who believe and stand with Gracie and Grant Solomon."

This means you, and that brave girl, are not alone. The video is well made - somebody or some group is helping her out. Whoever is responsible for that video will have your back, but I doubt you need to do anything more. Take care of yourself - keep an eye on Gracie's story but maybe don't try to take it on anymore than you have. You done good!

The fact that this girl has somehow come up with the internal fortitude to do what she's done is the part of the story that is hard to believe. Pretty amazing. Let's hope she and her brother get the justice they deserve. It looks like there are people out there helping her.

The only problem with the video is that there is no call to action. How do we help?
