there is little difference between the left and right, rabin , begin, sharon.
I didn`t see kahane saying any of these people should be shot.
Besides the fact that I am sure it is most probably against halacha. (if you cannot show that it is halachically acceptable, then murdering somebody is against halacha)
It just isn`t smart. It did not stop Oslo or remove the arabs. It did no good, it got peres elected.
And Yigal Amir was so blatantly allowed to get close to rabin, he was most likely working for israeli intelligence. AGAINST THE RIGHT. Just like avishai raviv, his purpose was to make the right look extreme so people would vote left. And they did. He was not an idiot either, he was a trainee lawyer. And in the trial he was trying to incriminate himself, calling for another witness when one showed how he couldn`t have done it, it is very odd. But painting this guy as an extreme right winger is just very far from reality.
Chamish - without providing a source - mentioned that Carmi Gillon described in detail the appearance of the murderer. Something like "a person may murder rabin, he may be curly haired, sephardi, from bar ilan university".
That matches yigal amir. And is more than coincidence.
Even if you oddly support his action. Do not support him.
