Absolutely agree. Holywood and particularly the video gaming industry need to be examined and REAL research done on the desensitizing effect of video gaming by young men. I believe the schools should institute an armed teacher program, similar to the airlines’ armed pilot program, which teaches not only firearms use but also hand-to-hand techniques to overpower attackers. There should be arms-qualified teachers in each school and weapons on the school property, readily available. On a personal level, we all need to learn how to protect ourselves and our families, starting with concealed carry. Teach your wives and children to be aware of where they are at all times; to be alert for abnormal behavior; to constantly scan for places to hide and escape. And, yes, I totally agree with locking up the mentally ill. Their families will thank you, believe me.
Maybe you can explain what caused mass killings before video games. There were a lot of them over the centuries.
