Students from at least 10 South Florida high schools have staged walkouts to protest Trayvon Martin's death, CNN affiliate WSVN reported.

Video from a WSVN helicopter showed students gathered on the Southridge Senior High School football field near Miami, standing in a formation that, when viewed from above, formed the letters "T" and "M"  Trayvon Martin's initials. At Miami Edison High School on Friday morning, more than 900 students gathered at the school's track to demonstrate for an hour. 

High school students aren't the only ones planning protests. In Dallas, people at Paul Quinn College planned to protest Martin's death. Other student-run organizations, such as the Black Graduate Student Organization (BGSO) at Carnegie Mellon University in Pittsburgh, are planning to rally next week. 

​Wow. Has there been another recent case when so many young people were organized and committed to activism, or would we have to go back decades to find another example?
