Another school shooting by a minor. What do you think should happen to the gun owners?

Another 14-year-old shot and killed 2 students and 2 teachers. I am so sick of hearing these stories. I think if you purchase a gun you should have your gun secured. It was sold to you. Not a minor. If it’s not on your person then it should be locked away or on the person of your spouse, but never out of sight unless locked away. Parents take chances with their children’s safety and they believe it’s their right but it’s not their right to risk the lives of others.
So that you know, I have guns and secure them when others are in my home. Especially when they come with minors. I put them in a safe.
