Seven years ago yesterday, Rachel Corrie, a 23-year-old student from Olympia, Washington, and peace activist with the International Solidarity Movement, was murdered while attempting to prevent an Israeli army bulldozer from demolishing a Palestinian home near the southern Gaza city of Rafah Basically, she was crushed to death by an US Caterpillar D9 bulldozer which plowed dirt over her, and then, with itâs blade lowered, backed over her half buried body, breaking her back and killing her.
