I wish an objective, non-political, archaeologist would have looked at whatever evidence this guy looked at. While most people think the Philistines originated somewhere in the Mycenaean world (Cyprus?), some think they came out of the region of the Hittite Empire. Although the idea of a Philistine kingdom north of Lebanon seems absurd, what he saw, if indeed it is Philistine at all, could shed some light on origins.
An investigation of this clown should begin, followed by a tenure hearing, and he should be booted and blackballed.
