The exact nature of her death and the culpability of the bulldozer operator are disputed, with fellow ISM protestors saying that the Israeli soldier operating the bulldozer deliberately ran over Corrie, and Israeli eyewitnesses saying that it was an accident since the bulldozer operator could not see her. The Israeli army conducted an investigation, which concluded that the death was an accident, and that the driver of the bulldozer could not see Corrie due to limited visibility from his cab. Amnesty International and Human Rights Watch as well as B'Tselem and Yesh Din criticized the military investigation.
