Rabbi Dahlia Bernstein, of Temple Beth Orh in Bellmore, says the deadly shooting at the Tree of Life Synagogue in Pittsburgh on Saturday hits close to home.

She says the Pittsburgh synagogue’s rabbi, Rabbi Hazzan Jeffrey Myers, had previously served at the now-closed Congregation Beth-El in Massapequa.

“The fact that we know one of the people there I think is just leaving us very upset,” she says.

The incident also has Rabbi Bernstein and other congregants like Arnel Halper, of Lindenhurst, thinking about increased security inside and outside synagogues.

Arnel and others say they're concerned about copycat incidents, especially on Long Island.

FBI officials say the alleged shooter Robert Bowers targeted the victims "simply because of their faith."

Rabbi Bernstein says even though security needs to be addressed, she says the root of the problem is prejudice and hated 

“One of the most important things for me right now is for all of us to feel unified and for all of us to embrace love and connection rather than hate,” she says.
