Mitchell Silber, having served as the director of intelligence for the New York Police Department, and more recently provided security advice for Jewish communities throughout Europe, recommends some measures for combating anti-Semitic violence:
[D]eterrence is crucial. Would-be assailants need to be dissuaded from carrying out attacks. In recent days, the mayor’s office has committed to deploying extra law-enforcement resources to the most endangered communities, [mainly] in Brooklyn. This is a good start, but the commitment must go further. Increased police patrols, the establishment of fixed posts, and even the use of undercover officers, dressed as observant Jews, are tactics that should be deployed and sustained for the foreseeable future. Removing these resources after only a short time has proved to be ineffective; incidents return as patrols leave.
The data also show that almost two-thirds of the attacks in New York City are committed by juveniles who are local residents. This is deeply disturbing. After suspects are arrested, family-court judges have too few options. City Hall must develop an age-appropriate, restorative-justice option for those adjudicated as juvenile offenders for their participation in what could be a hate crime.
Lastly, there is self-defense. The need for this is unfortunate—in part, it’s a failure of the American promise of freedom and toleration that a minority group must learn to provide for its own defense; but we must confront the world as it is. The Jewish community must be proactive in protecting itself.
