According to the Giffords Law Center, which was founded by former Rep. Gabrielle Giffords, D-Ariz., and her husband after she was wounded in a 2011 mass shooting, states passed 69 gun control measures in 2018, the most in five years. “I think Parkland was a turning point in the gun debate, that the students injected new passion into the gun control movement and pushed gun control to the top of the Democratic agenda,” he said. It’s been one year since Parkland, 16 months since Las Vegas, two and a half years since Pulse, seven years since Sandy Hook, 20 years since Columbine, and 25 years since Brady Background Checks were passed into law.
