According to Pro Publica, bin Laden once rejected the idea of creating a modified killing truck, apparently feeling like it was out of line, even by his standards.
The magazine, called Inspire, "apparently discussed using a tractor or farm vehicle in an attack outfitted with blades or swords as a fearsome killing machine," the official said. "Bin Laden said this is something he did not endorse. He seems taken aback. He complains that this tactical proposal promotes indiscriminate slaughter. He says he rejects this and it is not something that reflects what al Qaeda does."
