On Valentine's Day 2018 a gunman entered a high school in Parkand, Florida and opened fire. By the time he was apprehended there were 17 dead including teachers and students. The massacre became a warrior cry for the students. They raised their voices to demand stricter gun control laws and it swept across the country. It's not the first time people in the U.S. have called for gun restrictions after a mass shooting. But this time the students of Parkland had momentum and that turned their moment into a movement.
