Soon after the end of the M23 rebellion that threw parts of eastern Democratic Republic of the Congo (DRC) into conflict for much of the last two years, a blog post titled "We Stopped M23" appeared on the website of a California-based nonprofit called Falling Whistles. The slick homepage describes the organization as “a campaign for peace in Congo." It urges visitors to “be a whistleblower for peace” by purchasing stylish metal whistles, hung on a chain or black cord, from the organization's online store.
