On February 14, 2018, a school shooting took the lives of 17 people and suddenly changed the conversation about guns in America.
The shooting at Marjory Stoneman Douglas High School could not be called "the deadliest" or even "the most shocking" mass shooting in recent US history. It came less than five months after 58 people were shot and killed at an outdoor concert in Las Vegas, and nothing changed. It came less than two years after 49 people were shot and killed at the Pulse nightclub in Orlando, and nothing changed. There were 345 mass shootings in the US in 2017 alone, and nothing changed.
But this time, something clicked.
