Students from Marjory Stoneman Douglas High School in Parkland, Florida, where 17 people were killed in a mass shooting on Wednesday, on Sunday announced "March for Our Lives," a demonstration for new gun control legislation scheduled for Saturday, March 24, in Washington, D.C., and cities around the country. "People are saying that it's not time to talk about gun control. And we can respect that," said Cameron Kasky, a Marjory Stoneman Douglas junior who explained the event on ABC's This Week. "Here's a time: March 24 in every single city. We are going to be marching together as students begging for our lives," Kasky continued. "At this point, you're either with us or against us." He made a similar statement on Fox News Sunday.
