The latest spokesperson for police reform in the District wears a Tweety Bird jean jacket. Laura Munoz, age 10, got embroiled in an argument with an officer in Mount Pleasant in January—because, she says, the cop was rebuking her Colombian-immigrant father for speaking Spanish. Online public-safety activist John Aravosis heard about the incident through a friend and saw a chance to expand his police-watchdog crusade. By Feb. 20, Laura—billed to the media by Aravosis as “the Latin Rosa Parks”—was telling her story in front of police Chief Charles Ramsey, reporters from the Washington Post, El Tiempo Latino, and El Pregonero, and a crew from the local Univision affiliate. On Feb. 24, she turned up at a D.C. Council Judiciary Committee hearing but let her father do the talking. “It’s really weird,” Laura says. “I’ve never, like, been on T.V. or stuff.”
