Amidst a national debate regarding methods of protest and activism, students at B-CC High School in Bethesda have once again shown our community how it’s done. I recently attended an exhibition by B-CC students hosted by Artomatic, the annual showcase of visual art, music, film, performance and poetry. Organized by B-CC teacher David Lopilato and timed to coincide with the 25th anniversary of the Columbine school shooting in Colorado, the student art dealt with the issue of gun violence.
