I visited his website when I heard he was the one that handed over the photos of Abu Grabu. I then emailed the A-Hole and told him what I thought of him. He replied and told me to go take my meds.

When I was at the Army War College, I knew some officers who had been junior officers with Hackworth. To a man, none of them liked the guy or had anything kind to say about his war record. I loved his book "About Face" and more than once I was told, "if you only knew this guy you would feel differently."
Turns out they were right. Hackworth is a disgrace.
