More than 500,000 teens and adults are expected to rally in Washington, DC, this weekend at the March for Our Lives, a national protest against gun violence.
The "March for Our Lives Town Hall" was an opportunity for students to exchange stories and get inspiration from people who've lived through gun violence.
In Potsdam, the March for Our Lives will be an actual march. Arrested shortly after the shooting, the 19-year-old could face the death penalty.
"It's nerve-wracking", said Jain.
"What we have done, too, is have additional school security on campus", said officer Christopher Hawkins said.
It's images like the ones from the Parkland, Florida school shooting of students running for their safety that has the marchers organizers saying enough is enough.
The main march is in Washington D.C., but there are 840 events happening around the globe in far flung places like Japan, Iceland, Lithuania and Ghana, according to the March for our Lives website. They contacted the NYPD and summoned around 400 volunteers from schools and the public to assist along the march.
"We've just been there to make sure their voices are being amplified, and that the focus is on them and what they want and what they want to say", DeFelice said.
"We were all working together, doing t-shirt fundraisers and contacting different companies", said Moriarty.
Moriarty is from Broward county, and went to a high school neighboring Marjory Stoneman Douglas. "That was a part of the Driller Way, so to see that, to see how our school handled that situation, I liked it." said Zaragoza. Stars such as Justin Bieber and Harry styles have also encouraged students to participate as well.
Milwaukee Mayor Tom Barrett praised the young leaders he stood next to Friday morning for organizing the march.
Across the nation, thousands of students will march for change Saturday.
"In my life time there have been so many school shootings, and I've been through school shooting drills, and it was a normalized part of the culture".
