The Anti-Defamation League (ADL) called the incident heinous and not surprising.

In the wake of the escalating conflict between Israel and Hamas, the FBI is warning threats against the Jewish community are reaching historic levels.
Jewish leaders say it's more important than ever for everyone to speak out against hate.
"The moral voices of the community are actually much, much stronger and more powerful than the people who want to commit acts of antisemitism. And if we all speak out, we can actually overpower it," Trestan said.
As the LAPD investigates the case here, the FBI is looking into cases across the nation using joint terrorism task forces.
