The group alleged to have planned to blow up the PATH train tunnel apparently got the map on the Department of Homeland Security’s website:

The tunnel terrorists got their maps of the region’s vital underground passageways off the Department of Homeland Security’s Web site, sources said yesterday.

Maps of the city’s tunnels — including subways, PATH tubes and the Holland Tunnel — were found with the group’s reputed mastermind in Beirut, and were e-mailed to other members of the group, officials said yesterday.

Homeland Security did not comment on the report that its own Web site was used by the terrorists.
