NEW YORK - The American FBI have begun measuring radiation around hundreds of mosques. The tests that have been carried out in New York, Washington, Chicago, Detroit, Las Vegas, and Seattle are done to discover Al Qa'ida nuclear weapons. Washington is very worried about the growing amount of messages that Osama bin Laden wants to attack the US with either chemical, biological, or nuclear weapons. The FBI had done this without permission from a judge, but claim it is lawful because they were carried out on public highways. Opponents claim it is an invasion of their privacy.
