It's a strange case undoubtedly, but perhaps even stranger when taking into account a few things, like the possibility of forced medication. It has been reported that Raub had made claims that one of the psychiatrists involved in the case threatened him with forced medication. For history polymaths, government proposals of forced medication may not be a surprise and the case of Susan Lindauer may be remembered.
The situation may seem more or less strange when harkening back to 2009, when Fusion Centers targeted Ron Paul supporters, certain universities, and conspiracy theorists as threats to national security, even logging anti death-penalty and anti-war activists into federal terrorism databases.
Personally, I find myself wondering what sorts of epic dangers someone like Noam Chomsky might seem to pose after a stressful day and a few beers, if overheard by certain departments.
