If Israel and Sharon truly had no idea what was going to occur then they must be the most ignorant people alive. To think nothing would occur sending in the Phalange to a camp full of Palestinians, whom they'd been fighting for 7 long years, is just preposterous. Furthermore, it was Israel's responsibility, under Geneva conventions as the occupying power, to protect the innocents in those camps. There was a very interesting investigation into the events, including eye witness accounts, provided by the BBC. Entitled, "The Accused", here is a transcript of the show.
