13 injured. Two dead were pulled from the building, one presumably the pilot, another presumed to be a victim of the attack. With approximately 190 IRS employees who work there, it's amazing that there weren't more victims.
The suspected suicide pilot was Andrew Joseph Stack, a computer software engineer who posted an anti-IRS tirade on a website before setting his house on fire and flying a plane into an IRS building.
I express sympathy towards the victims of this senseless attack. Violence against civilian government workers, no matter what the political ideology, is wrong.
