During Shabbat morning prayer services at Congregation Beth Israel in Colleyville, Tex., Rabbi Charlie Cytron-Walker let in a man who was asking for help. The man soon turned a gun on the rabbi, holding him and three other congregants hostage in a harrowing 11-hour ordeal. He ordered the rabbi to call the leader of Central Synagogue in New York City, Rabbi Angela Buchdahl, and demand that she free a convicted terrorist serving an 86-year sentence. The idea that a rabbi could overturn a criminal conviction at the drop of a hat is such a stereotype of a stereotype that it's almost comical. And yet it is precisely this type of absurd conspiratorial thinking that presents the greatest threat to Jewish lives.
