9/11 Exposed - "The Dancing Israelis"

A group of Israelis with connections to Mossad were caught and linked to an Israeli spy group that were caught spying on important U.S. government infrastructure, FBI buildings, military bases, even caught walking the halls freely in the Pentagon. Most of the Israeli spies caught were explosive and communications experts posing as starving art students. Why do most people not know this? And most important why were some of them set up before 9/11 happened to record that horrific day and caught dancing after the first plane hit? There are no coincidences.
