This particular arson problem isn’t being perpetrated by Palestinians or any other anti-Israel terrorists. It’s a running feud among rival gangs of Eastern European Jews. In this case, shooting Palestinian teens in the head or knees is ineffectual.
It’s occurring in other parts of the country being done by Palestinians as well. The Jew gang problem will solve itself at some point or locals will take hold of the rival gangs and bash their heads. The gangs need to remember what brought them to Israel, the hatred of their Jewishness in Europe.
