Whatever of it had been has been destroyed. Any PA records have been "collected as evidence" by the IDF so it may be difficult to show who's missing in Jenin or anywhere else. How convenient. Do you suppose that was planned?
I would not deny there has been a wave of anti-Semitic acts in many places. While these acts are not independent of events on the West Bank, most definitely they are wrong. They are cowardly acts of small minded idiots. But, peaceful public demonstrations protesting Israeli actions are proper.
To cry "Anti-Semitism!" when you are criticized for barbaric acts is not becoming.
As you well know, the refugees in question are people who are not allowed to return to their homes in what is now Israel. It's an ever lurking problem Israel does not want to face.
