Here is video of the vicious stone attacks on Zehava Weiss and others' cars in Beit Ummar last week:
Apparently, because AP And AFP uncharacteristically released good photos of the incident, prompting Israeli media to cover the story, Channel 10 in Israel managed to find an actual videotape (since many reporters were there waiting for cars with Israeli plates to be stoned, some with video.) I don't know which service took this video.
Chances are that the tape would never have been released if it wasn't for the publicity. It isn't newsworthy on its own.
Yesterday, the uber-moderate PA prime minister Salam Fayyad described incidents such as these as "non-violent."
