On February 14, 2018, a mass shooting occurred at Marjory Stoneman Douglas High School in Parkland, Florida, resulting in 17 deaths and injuring 17 others. The assailant, 19-year-old Nikolas Cruz, was armed with an AR-15-style rifle. Cruz had a history of behavioral issues and had been expelled from the school, which added to the shock of his actions. The shooting unfolded in a matter of minutes, as students and staff sought shelter from the gunfire. Emergency responders arrived quickly, but the tragic loss of life had already been inflicted. The incident led to immediate national media coverage, drawing attention to both the specifics of the shooting and the broader discussions surrounding gun violence in America.

In the aftermath, students from Marjory Stoneman Douglas High School became vocal advocates for gun control, organizing the 'March for Our Lives' demonstration in Washington, D.C. The movement aimed to bring attention to the need for legislation that would make schools safer and limit access to firearms, particularly semi-automatic weapons. The event galvanized a new generation of activists and inspired discussions about mental health, school security, and the political power of youth.

The shooting resulted in significant changes at local, state, and national levels regarding gun legislation, school safety measures, and mental health support. Conversations surrounding the Second Amendment grew louder, and various aspects of American society began to reckon with the implications of gun violence and mass shootings. Nikolas Cruz was arrested and later charged with 17 counts of murder, making this act one of the most pivotal moments in the ongoing debate over gun rights and public safety in the United States.
