Insanity? Terrorism? Senility? Murder.

In a video game, a conspiracy-theorist radio host asks if his callers could please just make sense.

In life, though, I wonder the same thing about, well, yeah ….

In von Brunn’s car outside the museum, authorities found a handwritten note, according to the affidavit: “You want my weapons — this is how you’ll get them. The Holocaust is a lie. Obama created the Jews. Obama does what his Jew owners tell him to do.” There were other anti-Semitic rants, followed by: “The 1st Amendment is aborgated — henceforth.”

There is actually a lot to consider about the Holocaust Museum shooting. But while some would make the hay about the obvious—that the DHS report on right-wing extremists might well have been accurate, for instance, or connecting angry, right-wing talk show rhetoric to extremist violence—there is something else, perhaps more subtle, that begs notice.
