The U.S. government has long offered rewards for its most wanted terrorists as a way of incentivizing people to be on the lookout. Its success obviously relies upon widespread knowledge of the award and what the terrorists look like.
For the Council on American-Islamic Relations (CAIR), a U.S. Muslim Brotherhood entity, the fact that Americans would become aware that majority of the most-wanted terrorists are Islamic extremists compelled it to take action. As usual, CAIR cried "Islamophobia," deployed its interfaith partners and was successful in having the most-wanted terrorist ads taken down.
The U.S. government posted ads on buses in Seattle that said, "Faces of Global Terrorism." Their purpose was to notify citizens that up to $25 million could be earned for information leading to the neutralization of 16 top terrorists. OnIslam.net explains that 7 of the terrorists are from Africa, 4 from the Philippines, 3 from the U.S., 1 from Malaysia and 1 from Chechnya.
