The rules of Rodef, however, apply even in the absence of a Sanhedrin (Rambam Hilchot Rotze’ach 1:6-13 and Shulchan Aruch Choshen Mishpat 425). In fact, the Rama applies the Halacha of Rodef to one who engages in forgeries. Government authorities in the past imposed severe collective punishments (including executions) upon the Jewish communities in which a Jewish forger resided. Thus, the forger endangers the community and is treated with the severity of a Rodef.
Rabin’s assassin had no Halachic basis to shoot Prime Minister Rabin. Professor Schochetman notes that the shooting caused grave damage to the opposition to the Oslo process. Moreover, it caused a profound Chillul Hashem whose impact we experience even nine years after the shooting. Professor Schochetman (paraphrasing Teshuvot Chavot Yair 138) correctly describes the shooting of Yitzchak Rabin as "an foreign, evil, and bitter act." It is foreign to the Jewish people, it has no Halachic basis, it is morally reprehensible, and it has had bitter ramifications for Israeli society.
