T.C. Williams High School students Hannah Miller (left) and Jay Falk organized a day against gun violence on Tuesday. Their #WeAreAllEagles event was adopted by the school, prompting over 1,000 T.C. students to wear ribbons and the school colors of Marjory Stoneman Douglas High School in Parkland, Fla., which suffered 17 deaths from a shooting on Feb. 14.
