A bill filed in the Florida legislature by a South Florida Senator would require that silent panic alarms be installed to link public-school buildings to local law-enforcement agencies. Senate Bill 174 – called Alyssa’s Law,” after Alyssa Alhadeff, a 14-year-old student who was one of the 17 people killed in the February mass shooting at Marjory Stoneman Douglas High School in Parkland – would require each building on public elementary, middle and high school campuses be equipped with at least one panic alarm for use in non-fire evacuations, lockdowns or active shooter situations. The bill was filed by Senator Lauren Book, from Plantation, Florida.
