As John Doraemi makes clear in this excellent analysis
there were at least two "vans" stopped, searched and seized in New Jersey on 9/11, resulting in the apprehension of at least seven suspects.
The first van, associated with the "dancing Israelis" seen filming the North Tower strike in Liberty State Park, was stopped "on Route 3 in East Rutherford around 4:30 p.m."
A second van was stopped on or near the George Washington Bridge several hours later. CNN's Deborah Feverick cited "two sources" claiming that "law enforcers found tons of explosives" inside this vehicle. http://transcripts.cnn.com/TRANSCRIPTS/0109/11/se.04.html Dan Rather and the Jerusalem Post echoed this report.
Two events, miles and hours apart.
Now consider the Port Authority Police Department Reports, Group 2, pg. 52.
