The legislature's Education Committee voted in favor of a bill to include Holocaust And Genocide Education And Awareness in social studies curriculum.   Co-Chair Senator Toni Boucher proposed the bill in response to anti-Semitic graffiti found in her district recently, in Ridgefield.  She notes that the Holocaust survivors and children of survivors are aging and the eye witnesses to the atrocities that took place nearly 80 years ago are being lost.  Boucher says she doesn't want the knowledge of this sad chapter in world history to disappear with them.
