PITTSBURGH — One day after a vehicle tossed fliers denigrating Jews throughout the historic Jewish neighborhood of Squirrel Hill, shouting antisemitic epithets as they went, Yaron Lischinsky and Sarah Lynn Milgrim were gunned down outside the Jewish Museum in Washington, D.C.

The horrific murder, along with the constant targeted intimidation tactics in Jewish communities, as well as on the campuses of the country’s elite universities, has left Jews across the country rattled.
