Halachic Analysis: “Excessive Force” Against Knife-Wielding Palestinians

shaar shchem attack (2)By Rabbi Yitzchok Grossman

Recently,  as Israeli security forces have often responded to knife-wielding Palestinian attackers by shooting them dead, they have been criticized, not just by Arabs and Palestinians, but even by U.S. government officials and international and even Israeli humanitarian organizations for utilizing “excessive force”.1 Israeli Defense Minister Moshe Yaalon considers this preposterous: “We are using excessive force? If someone is wielding a knife and killing people, [then our response is considered] excessive force? What are we talking about here? This is nonsense.”2 In this article, we considerhalachah’s perspective on the use of lethal force to counter a lethal threat where non-lethal action would be sufficient to neutralize the threat.

The Obligation To Utilize Non-Lethal Force

The halachah is that the dispensation to kill a rodef (“pursuer” – i.e., someone pursuing someone else with lethal intent) does not apply where thenirdaf (“pursued one” – i.e., the rodef’s target) can be saved3 by merely maiming the rodef. A rescuer who nevertheless chooses to utilize lethal force is guilty of capital murder,4 although it is disputed whether this means that a [terrestrial] court will actually execute him.5

From a practical perspective, the obvious difficulty is ascertaining whether non-lethal force is really a viable alternative. Police officers commonly retort to those who criticize them for the use of excessive lethal force that “shooting to wound doesn’t make sense scientifically, legally or tactically”.6 The Talmud itself cites contention over this point as far back as the era of the Neviim: During a military clash between the forces of David Ha’Melech and those of Shaul Ha’Melech’s son Ish Boshes, Asahel (a member of the former) pursued Avner (a general of the latter), and Avner was forced to kill Asahel in self-defense.7 Asahel’s brother Yoav subsequently avenged his death by killing Avner.8 The Talmud relates that when Yoav was challenged over this murder, he asserted that he was the go’el ha’dam (“blood avenger”)of Asahel, whom Avner had unjustly killed. Upon being told that Asahel was a rodef, Yoav retorted that Avner should have tried to neutralize him using non-lethal means, and in response to the suggestion that Avner had been unable to, Yoav pointed out that Avner’s death blow against Asahel had exhibited extraordinary precision in its lethality, and that it was therefore inconceivable that he would not have been able to neutralize him using non-lethal means.9

The Nirdaf Himself

Several acharonim point out that the above dialog implies that even the nirdaf himself may only kill in self-defense where non-lethal means are impractical,10 in apparent contradiction to the position of some acharonim that the obligation to utilize non-lethal means only applies to other rescuers, and not to the nirdaf himself.11

The basic idea that the nirdaf himself has more latitude to save himself by killing the rodef than other rescuers have, has precedents in the rishonim: there is an opinion that while a rescuer must generally warn the rodef before killing him, the nirdaf need not do so, “as he is urgently concerned with his life, to save himself”,12 and there is an opinion that a woman whose difficult childbirth is endangering her life may destroy her fetus in order to save herself even after its head has emerged, despite the fact that others may not do so on her behalf.13

3 The Talmudic phrase “niten le’hatzilo” may refer to saving either the nirdaf from death, or the rodef from the perpetration of murder. See Tosafos Sanhedrin 73a s.v. le’hatzilo; Hagahos Ve’Chidushei Ha’Rashash ibid. 49a.

5 See Yad Ha’Chazakah Hilchos Rotzeach U’Shemiras Nefesh 1:13; Kesef Mishneh ibid.; Tur, Beis Yosef and Bedek Ha’Bayis Choshen Mishpat siman425; Mishneh Le’MelechandMa’aseh Rokeach ibid.

7 Shmuel 2 2:18-23.

8 Ibid. 3:26-27.

9 Sanhedrin 49a. It is not entirely clear whether Yoav’s defense asserting that Avner’s failure to utilize non-lethal means rendered him a murderer was accepted; see Yad Ha’Melech and Tzitz Eliezer cited at the end of n. 11. A subsequent passage in the Talmudic discussion has this debate taking place between Yoav and Avner himself prior to the former’s murder of the latter.

12 Shut. Rivash end of siman 238, cited in Mishneh Le’Melech ibid.

13 Beis Ha’Bechirah Sanhedrin 72b (citing “the sages of the generations that preceded us”)

  1. In this analogy or in general the din of rodef, as I see it, is when a Jewish person is chasing a Jewish person. In Israel it is the case of a goy trying to kill a Jew are the laws the same? Especially when you wound an arab he will eventually come back to try to kill a jew in the future as we have seen time & time again.

  2. This writer, as beautiful as it is, misses a huge point, the above lomdus is for a Yid not a goy! Especially not a nation at war with the Yidden!!!!

    If one doesn’t kill them and he is able to, he may be liable for the other killings done by the enemy. Not to mention, this idiotic practice of treating terrorist who have been shot. These only help encourage more terror!!!!!

    This is the second time I’m reading a article like this. It would be more prudent to write articles that actually are nogeia. Please don’t put doubt in the minds of the people facing terror

    The message should be loud and clear
    Shoot to Kill and if u missed shoot again, until he is dead. Do not give terrorist medical treatment let them lay there winded until they die!!!!

  3. This is not a good example. This took place during a war and both sides were soldiers and Jews. However in the present situation the victims are often innocent civilians and the perpetrators are not Jews. I am sure the Gemara addresses such situations as well. Why not bring those?

  4. No discussion of the chiyyuv misah of a goy who wounds or kills? No discussion of applying the din milchamah to the Arab struggle against the Yidden?

  5. It is so plan and simple: The Torah teaches us clearly: “Someone comes to kill you, you have an obligation to kill him first”.

    Plain and simple.

  6. I was thinking this is different considering they are not jews.But What If a decent percentage of the muslims might descend from Jews who converted to christianity and then to islam or directly to islam?

  7. This article was clearly written as a discussion of the laws of rodef as it applies between Jews. It was not meant to be political advice or a discussion on the practicality of determining whether lethal force is necessary. The news item, as it is in most of these halachic articles based on current events, is just a spring board for the discussion.
