None of this is available. We have no way to know if the research organization has any credibility, because we don't know who they are.
I'm sorry, but that's fairly ridiculous. We don't know who it is, which means they could make up any excusethe company doesn't want to be named because it does this sort of thing for the government, meaning probably our military/intelligence structures. This is part of how we find and kill bad guys.
We should also note that if they're doing intelligence work (e.g. an NSA subcontractor), then that data is probably classified, and releasing this data would be a serious legal violation, and they'd probably be identifiable to whoever is in charge of that contract. Isn't wild speculation about anonymous sources fun?
No, you can't, because the article did NOT say that the person calling for the purge was one of the alleged 20-50 ringleaders. Read it again.You can, actually. That is what calling for a Purge means. No one is suggesting an ancient roman dining habit.
