In February, Marjory Stoneman Douglas High School in Parkland, Fla., was the site of one of the worst school shootings since Sandy Hook in 2012 where 17 people were killed and 17 others were wounded when an expelled student opened fire. Now, the school is enacting stricter security measures to ensure a massacre like the one on February 14 never happens again.

Most importantly, they’re doing it without gun control.
