The Black Student Alliance at Yale on Saturday is sponsoring a "Hoodies Up New Haven" march and rally in support of Trayvon Martin's family, the arrest of his shooter, George Zimmerman, and amending the Connecticut's Alvin Penn Racial Profiling Act to strengthen its enforcement.

The event begins at 3 p.m. at the Dixwell Community "Q" House, 197 Dixwell Ave. Participants will march to the New Haven Green for a rally and are encouraged to wear hoodies.

Martin, 17, was shot on Feb. 26 in Sanford, Fla. by George Zimmerman, a neighborhood watchman who claims he killed Martin in self-defense.

Martin's family is calling for Zimmerman's arrest and protests have erupted nationwide against self-defense laws, such as the so-called 'stand your ground law' in Florida.

Organizations co-sponsoring "Hoodies Up" with the Black Student Alliance include My Brother's Keeper, MEChA de Yale, NAACP branches at Yale, Southern Connecticut State University and University of New Haven, Connecticut African American Emancipation Committee, Unidad Latina En Accion, Phi Beta Sigma Fraternity, Yale College Democrats and Sigma Gamma Rho Sorority.

The public may follow updates on these activities using the Twitter hashtag #hoodiesupnhv.
