Fort Dix terror suspect Mohamed Ibrahim Shnewer was arrested in his taxi cab at the Philadelphia airport.

From various reports that have surfaced about the plot, it's clear that these terrorists were not the sharpest tacks in the pencil box. But one wonders how long was it going to take airport cabbie Mohamed Shnewer to figure out he had access to secure areas of the airport "big enough to drive a truck through." 

CNN reports on what Mohamed Shnewer had in mind when discussing how many soldiers he wanted to kill at Fort Dix — with an FBI informant taping the conversation:

"My intent is to hit a heavy concentration of soldiers. … This is exactly what we are looking for. You hit four, five or six Humvees and light the whole place [up] and retreat completely without any losses."
