This must be Manifesto Week.  The Norwegian right-wing fanatic posted a 1400-page treatise before bombing downtown Oslo and shooting 85 young people.  At least he didn't mention bitcoin.

So I'll amend my original post.  I still think it would take a pretty major event to trigger a rapid militarization of the internet and crackdown on bitcoin.  But it probably doesn't need to be on the scale of Pearl Harbor.

If this disturbed Norwegian had used bitcoin to fund the massacre, you can be sure the crackdown would be sure and swift.
