Sadly most have not heard of most of this due to the fact that at the same time back in the US all possible Israeli involvement in 9/11 was quickly deemed "classified for national security" and fully swept under the rug.
"Evidence linking these Israelis to 9/11 is classified. I cannot tell you about evidence that has been gathered. It's classified information."
-US official quoted in Carl Cameron's Fox News report on the Israeli spy ring and its connections to 9-11.

Suspicious Activities Involving Israeli Art Students at DEA Facilities
In January, 2001, the Drug Enforcement Administration (DEA), Office of Security Programs (IS), began to receive reports of Israeli art students attempting to penetrate several DEA Field Offices in the continental United States. Additionally, there have been reports of Israeli art students visiting the homes of numerous DEA employees. These incidents have occurred since at least the beginning of 2000, and have continued to the present. The number of reported incidents increased in November/December 2000, and has continued to date. These incidents have involved several other law enforcement and Department of Defense agencies, with contacts made at other agencies' facilities and the residences of their employees. Geographically, these incidents are very widespread, ranging from California to Florida. The majority of the incidents have occurred in the southern half of the continental U.S. with the most activity reported in the state of Florida. Since April 2001, the number of reported incidents has declined, however, the geographic spread of the incidents has increased to Wisconsin, Oklahoma, and Los Angeles.
