my name is laurie alhadeff, my daughter is alyssa alhadeff. she lost her life at school, shot three times. she was not able to be identified until 2:00 a.m. in the morning. along with 16 other parents who is lost their children, i am tired of people doing enough. this horrific incident has to be the catalyst that finally puts things in action. let's make our schools safe again, #alyssaalhadeff. in 2013, the nra released the 220-page report to call for more security at schools. it detailed security guards, teacher training, bomb-sniffing dogs, expanded police presence in schools. here we are, five years later and nothing has been done. our teachers need to be properly trained to teach our children how to handle a code red. we can visually mark hiding areas in the classrooms to protect our children from being gunned down. where are our metal detectors? where is our bulletproof glass? where are children's i.d. badges with the photos, names, and the ability to open locked doors? where are the new versions of amber alerts before school safety? wher
