An investigation means that it is confirmed that this is the manifest.
Question is, why is it damning? Who’s being exposed here to great harm by showing this?
I wish people would stop calling it a ‘manifesto’. It isn’t.
It’s a ‘Dear Diary’ entry full of weirdo racist hate as if she was a poor black child in a world full of KKK members.................
It shows once again that the government was well aware of this nut case having interacted with her several times.
Having lots of evidence that this was the likely outcome, like always they did nothing to prevent the mass shooting.
The great harm is exposing government incompetency and inaction, hence the government coverup.
