There was a shooting scare at the March for Our Lives rally.
The crowd jumped into action after a man yelled that he had a gun.
Brandon Farbstein, an activist who was present at the rally, told Insider that he wasn't sure if that came from security or someone else in the crowd. Everybody dropped like flies. We were so petrified of what was happening that we didn't know what was happening.
The US Park Police released a statement saying there was no risk to the public and that one person had been taken into custody.
The moment of silence was disrupted by a person in the rally. A spokesman for the March of Our Lives said there was no threat to the crowd. The organizers acknowledged the issue with the crowd and the program continued as planned.
There was a scare as demonstrators were participating in the March for Our Lives rally. The Uvalde, Texas, elementary school shooting that left 21 people dead and 17 others wounded was the catalyst for the rally.
The first March for Our Lives rally took place after a mass shooting at a high school in Florida.
"Not sure what morally depraved human decided the moment of silence for school shooting victims was a suitable time to start a counter protest and scare everyone into a near-stampede," one witness wrote on the social networking site.
The rally got back on track after the interruption, but there was a sense of fear among participants after the crowd surge.
It brought a lot of energy to the entire crowd. There were a lot of people who were traumatised by what they had experienced in the past and were trying to prevent this from happening to them.
It is an unfortunate example of why we need to keep doing this work.
