Judaism on trial in Russia

"Judaism on trial. After thousands of prominent Russians, including a chess champion and 20 members of parliament, demanded that Russia ban Judaism and Jewish organizations, the state prosecutor is investigating the Shulhan Arukh, a 16th century book of Jewish law (and early example of hypertext), for causing incitement and expressing anti-Russian views. Judaism used to be placed on trial regularly during the Middle Ages, and, except for a famous episode in 1264, it always ended badly for the Jews. So what is going on in Russia?"
