This whole story is hard to follow and I find no other source in the media.
However I get the impression the sign that was taken down by the Klein Collins student included a photo of the upside down US flag that was displayed in CA a couple of years ago. I’m not sure as this story is total incoherent to me.
They only write what feels good to them, never mind filling in all the facts
