In Orthodox communities around New York, families are “definitely scared and frightened,” Rockland County official Aron Wieder said in a phone interview.

“If you were to walk down any street in Rockland County in the Orthodox Jewish community you will feel it in the air,” he said. “Children are frightened. Parents are nervous to send their children to school,” he said. “You could literally feel it and maybe touch it even.”

Celebrations of the last night of Hanukkah would go on after sundown Sunday, he said, but will proceed with caution and a measured tone.

The spike in bias incidents against Jewish communities has law enforcement and elected officials wrestling with what to do.

At a news conference, New York Police Commissioner Dermot Shea said he could not believe he was addressing the public about anti-Semitic violence less than a month after the Jersey City attack.
