Siegel is entitled to her opinions.
I think she has described her actual experience honestly.

She saw no Israelis in the camps.
She saw a bulldozer clearing the ground by the southern entrance.
She saw no bodies being buried.
She said it was yellow so unlikely to be an IDF vehicle.

She reported that her party was saved from execution by an Israeli running from positions outside the camp, and given honey cake that soldiers' mothers had sent them because it was "their Christmas."
