The Israel Police was quick to label the murderers “Jewish extremists,” meaning they aren’t part of the herd, they are outliers, “wild weeds.” This is the police’s way of trying to justify a sin, to “make the vermin kosher.” But the vermin is huge, and many-legged. It has embraced the soldiers and other young Israelis who overran the social media networks with calls for revenge and with hatred for Arabs. The vermin was welcomed by Knesset members, rabbis and public figures who demanded revenge. Nor did it skip over the prime minister, who declared “Vengeance for the blood of a small child, Satan has not yet created.”
