Recent news that the New York Police Department presented the film “The Third Jihad” to nearly 1,500 officers is only the latest example of anti-Muslim training materials being used in ways that harm our national security.

The film baselessly contends that “the true agenda of much of Islam in America” is to “infiltrate and dominate America,” smearing a religion that has been part of this country since its founding. Incidents like these sound the alarm on the need for greater transparency and oversight of counterterrorism training at all levels of government.
