Want to help stop shootings? We as a country need to start educating people on how to be a better parent.
If a parent has any child in the house, no matter the age, they should lock up their guns to prevent said child from getting a gun. My parents have done it for Fifteen years and I just now found out we had a gun from hearing my parents talk.
Parents need to educate their own kids about what is real and not real. I watched Terminator 2 when I was 9 years old. Seem bad? I played M rated games at age 11. I saw violence at TV since I was 6, yet from the age of 4 my parents always told me about what was fake, and what was real. They educated me on the repercussions on killing someone, the mental effects, everything.
If you want to stop school shootings, and just shootings in general, be a good parent. Educate others to be good parents. Maybe as a country we can help do this. Maybe parenting classes for expecting parents? It won't stop the situation completely, but it will help greatly reduce a lot of shootings.
