I think I know the reason.
About a year ago, the US installed radiation detectors
at the US Canadian border.
Before the detection system was fully operational
it did detect radiation from an 18 wheeler truck
passing through
(at Detroit, I believe)
but the alarm system did not go off.
Authorities have been searching desperately for this truck ever since.

who has contacts with CSIS (the Canadian 'CIA')
and has reported frequently
on this not well publicised story
on WABC, New York)
Seems to me like truck bombs are a huge possiblity here; coupled with your friend's information, I think we should all keep our eyes open.
