“It doesn’t really matter the size of the city, because our whistles are very loud, and they can be heard up to two miles away,” says Megan Whilden, one of the organizers.
Jack Holmgren, a former immigration attorney and Carmel resident, spearheaded Whistlemania locally, saying a whistle is a tool people can use to alert others of ICE presence in real time. “It’s also a tool that can be used for nonviolent, civil disobedient resistance by the community that doesn’t have any concern about documentation,” Holmgren adds.
