A bomb was chucked at Tzippi Livni's house on Friday morning. Luckily, she wasn't at home. First report here in Hebrew

UPdate: It was a fire cracker, apparently, but there are still those sick enough in Israel to start with that again. Remember Yigal Amir. He didn't operate in a vacuum, there were a series of anti-Rabin demonstrations first, some of them quite vile (coffins, posters showing him in SS uniform...)
