According to Austin authorities, Joseph Andrew Stack or Joe Stack, a Texas man, has left a lot of innocent people in his wake. 13 people were hurt and two critically, after this man deliberately flew a small plane into a building where the Internal Revenue Service had about 200 workers.

“It felt like a bomb blew off,” said Peggy Walker, an IRS revenue officer who was sitting at her desk. “The ceiling caved in and windows blew in. We got up and ran.”

Authorities said that Stack worked alone. He was presumed dead, and police said they had not recovered his body.

The FBI believes that Stack left a twisted suicide note / bomber’s manifesto on the Web two days before the crash in which he ranted against the IRS, the Catholic Church, tax loopholes, bailouts and his own sorry state of affairs.

The suicide note read:

If you’re reading this, you’re no doubt asking yourself, “Why did this have to happen?” The simple truth is that it is complicated and has been coming for a long time. The writing process, started many months ago, was intended to be therapy in the face of the looming realization that there isn’t enough therapy in the world that can fix what is really broken.

Joe Stack was angered by a “handful of thugs and plunderers (that) can commit unthinkable atrocities” including bailed out GM executives and the drug and insurance companies who “are murdering tens of thousands of people a year and stealing from the corpses and victims they cripple.” He hoped that the “the American zombies wake up and revolt,” and at times expressed that he was at a breaking point.
