Counterterrorism officials told Fox News that they are especially concerned about the possibility of a truck bomb and said an influx of credible intelligence has been received suggesting that Al Qaeda may be contemplating such a bomb.
I know personally of 4 to 6 cases of middle eastren men trying to buy 18 wheelers for personal use with cash (the 18 wheelers cost about 115,000 dollars!?!?), the fbi was called, but i don' know if any arrest were made.
Just so you know the fbi is not blowing smoke up you ass, they are doing one great job. And hopefully no lives will be lost.
