It’s interesting; there are earlier sites in Egypt, including one which was apparently stormed by an attacking force, which left thousands of arrowheads, burned everything, killed or captured everyone.
I had the opportunity to wander the Fayoum area. We left all artifacts, like arrowheads in place. But we heard rumors of U.S Embassy employee(s) who had a trunk full of the things. It was just a rumor, of course.
