According to the newspaper, Big Al sat respectfully at the back of one Boro Park shul, and "as worshipers swayed in prayer, known as shuckling [a guy] said he saw Mr. Pacino slowly rock back and forth with them, observing their movements."

Additionally, as Lipman adroitly observes, why he thinks he can learn anything about a 15th century Venetian Jew by observing Hasidim is anyone's guess.
