Baltimore students are planning a March For Gun Safety today. They've prepared a list of demands and a code of conduct and are using the hashtag #gunsdowngradesup 
"Students were willing to walk out, to let go of whatever test or project they had and put their energy towards the protection of their friends," said Cassius Comfort, a senior at Friends School.

Charlotte Corcoran, 14, is supposed to be in English class right now at Roland Park Country School.
The hundreds of students marching have made it to Johns Hopkins' campus. "This whole experience is surreal," said 16-year-old march organizer Amee Rothman. "Students can make a difference and our voices will be heard."
Chants of "Grades up! Guns down!" as hundreds of Baltimore students protest gun violence during a school walkout. One girl just turned around, looked at the massive line of students and said to her friend: "Wow, that's all us."

"America needs to hear the voices of the young people of Baltimore," said @MayorPugh50, discussing plans to bus students to Washington for the March For Our Lives event on March 24. "The gun violence has to stop."
"Every day when you come to school you have a right to learn, you have a right to be safe," @Darryl_De_Sousa said. "I stand beside you 100 percent. Enough is enough."
Unique Chisholm, a 17-year-old from Dunbar, said "something needs to change." She thinks you should be 21 to get a gun and have to pass a background check. She said it's good to see the kids of Baltimore for together for something like this.
The group from Baltimore City College has arrived. Kids are running to hug their friends as the plaza in front of City Hall continues to fill up.
"It is not cool to bring guns to school," said @Darryl_De_Sousa baltimoresun.com/news/maryland/…
