2. SOUNDBITE (English) Delaney Tarr, Student at Marjory Stoneman Douglas High School:
"Our childhood is gone because that man, that man despite being diagnosed with autism, ADHD, despite being evaluated and not even committed by a mental health facility, despite being tipped off to the FBI multiple times was able to legally purchase an AR15. He was able to legally purchase that semi-automatic rifle and come into my school and slaughter 17 of my people. Because of these gun laws, people that I know, people that I love have died and I will never be able to see them again."

4. SOUNDBITE (English) Cameron Kasky, Student at Marjory Stoneman Douglas High School:
"There are people from both sides who are saying, enough of these guns and it's not about that anymore. This is about painting a badge of shame to put on anybody who has accepted money from the NRA."

"This fight is not going to be easy, this fight is not going to be short. We're going to have to continue four days, months, years and decades because the people in the special interests that want to pass these gun laws to make it easier for these people to get guns are not going to stop and we can't either. We need to get out and vote."

"We've had so many other awful, just God awful events that have happened and now is the time that we say, thank you for your prayers and condolences but that is not enough, we are doing the same thing again and again and the same thing needs to happen when we say stop it, stop at today."
Hundreds of people turned out at an anti-gun rally in Fort Lauderdale on Saturday.
Survivors of the shooting at Marjory Stoneman Douglas High School spoke at the rally to condemn gun laws and rail against the National Rifle Association.
Delaney Tarr, who said she lost four of her close friends, expressed anger at how existing gun laws allowed for suspect Nikolas Cruz to legally buy the AR-15 semi-automatic rifle authorities say he fired Wednesday inside the school, killing 17 people.
Florida's child welfare agency investigated Cruz after he cut himself in an online video but found him stable, according to state records.
Cruz had been diagnosed with autism, a neurological disorder that often leads to social awkwardness and isolation, and attention deficit-hyperactivity disorder, or ADHD.
Cameron Kasky and David Hogg, who also survived the shooting, said thoughts and prayers are not enough anymore and urged people to get out and vote to help change existing gun laws.
