Saying that this story justifies the DNS memo seems a bit of a stretch. Here’s what John at Powerline had to say:

“Its strongest warning was against the possibility of veterans of Iraq and Afghanistan turning to violent, right-wing extremism, but veterans have been returning from Afghanistan since 2002 and from Iraq since 2003. An investigation of the circumstances under which this report was written and disseminated appears to be in order.”

I completely agree.
