After Attack, Some Jews Wonder How Much More Security Is Possible

In the eight years since a gunman killed 11 people at the Tree of Life synagogue in Pittsburgh — the deadliest antisemitic attack in American history — synagogues and other Jewish institutions across the country have gone to great lengths to fortify themselves.

They have hired security guards, installed metal detectors, reinforced locks, bought cameras and established checkpoints. They have logged onto security briefings and participated in training sessions for clergy members specifically focused on preparing for active shooter events.
