PARKLAND, Fla. — Thousands of people filled a park near Marjory Stoneman Douglas High School at a “March for Our Lives” rally near the site of last month’s school massacre in Parkland, Florida.

Saturday’s rally in South Florida had the feel of a campaign event. Students wore maroon T-shirts — the school’s color — and chanted slogans such as “Enough is enough.” They held signs that read, “why do your guns matter more than our lives?” and “our ballots will stop bullets.”

Organizers said 20,000 people were attending the rally.

After the rally, participants will march 2 miles to Stoneman Douglas. They will pass the school in silence to honor the 17 victims of the Feb. 14 shooting.
