How do you determine that someone is Jewish?
I guess he just focused on non-black victims and they happened to be Jewish.
Regardless, he needs to be put down like the other poster said.
Many Jews in that area are orthodox. Their style of dress, both for men and for women, is unmistakable.
Orthodox Jewish women cover their hair with either a kerchief or a wig, and dress modestly. How dare they. That deserves a bash on the back of the head./s
If their orthodox it’s not too hard
That area of Brooklyn has a large Hasidic (ultra-orthodox) community. Their dress and hair is distinctive.
In that neighborhood, someone who is dressed modestly in a long skirt wearing a hat or a very good wig is probably an Orthodox woman.
If someone is wearing traditional Hasidic garb, there is an excellent chance that person is Jewish.
