This is the evil side of archaeology. The land belongs to individual Palestinians. No consent from them have been sought or given. The excavation has largely been made by illegal Israeli settlers, who have used it to destroy Palestinian property on the site and nearby, including burning olive trees belonging to local farmers.

The claims made based on the excavation are politically based and can't be taken by face value, as the illegal Israeli settlers announced before the excavation began what they sought. The leading Israeli archaeologist involved had to be at one point constrained by Israel's own occupation troops from destroying more property, including one ancient olive tree.
