This is a real newspaper article, reprinted by the Sydney Morning Herald (Australia), from the Boston Globe:
Cars stolen in US used in suicide attacks
The inquiry began after coalition troops raided a Falluja bomb factory last November and found a Texas-registered four-wheel-drive being prepared for a bombing mission.
Investigators believed the cars were stolen by local car thieves in US cities, then smuggled to waiting ships at ports in Los Angeles, Seattle, and Houston, among other cities. Terrorism specialists said they believed Iraqi insurgents preferred American stolen cars because they tended to be larger, blended in more easily with US convoys, and were harder to identify as stolen.
Yes, that must be it. From the "it's so crazy, the dumbass American public just might buy it" school of thought.
