They marched, chanted and some held signs with anti-gun messages like one that read, "thoughts and prayers don't save lives."
This is the second nation-wide walkout since the mass shooting in February at Marjory Stoneman Douglas High School in Parkland, Florida, which left 17 students and educators dead.
Some students ABC7 News spoke with said they want to honor all lives lost to gun violence and want to send a message to politicians that change needs to start now. "We're walking to amplify the voices of those affected. We're here to stand up and see the change we want to see in the world because if we're not going to take a stand who else is," student Astrid Domniguez said.
