A small plane crashed into an Austin, Texas offiice building today. The building houses IRS offices. Authorities are saying that terrorism isn't suspected. CNN is reporting that the person believed to have piloted the plane may have set his own home afire before the crash.
UPDATE: Social media clues point to a long-running tax dispute as potentially at the root of this.
PS -- I agree with readers and meant to qualify this post originally to say the same thing. An act of violent retribution, such as this appears to be, smells an awful lot like a terroristic act to me, if not by a foreigner.
