21 airports fail bomb screening test

Investigators for the General Accountability Office conducted tests at 21 airports to test screeners' ability to detect bomb components powerful enough to blow up the trunk of a car. They successfully got the parts past security screening at all 21 airports.

The TSA responded by saying that the tests "failed to consider the full array of air travel security measures." That response doesn't seem to be to the point--the parts were successfully smuggled past security checkpoints, meaning that there was no effective countermeasure in place.
