I say don't.
Video games are an easy culprit for the politicians and others. I’m a geezer and I’ve been playing video games of all kinds since the early 70s, as an adult. My sons and their friends, and all of the young people I served with during my military career played them and I don’t know of one who has ever been noted as a mass killer.
In the 50s and 60s it was rock music, along with TV, along with beach movies. In my parents generation it was jazz, swing. Each generation has had social conventions that were blamed for the upcoming downfall of civilization.
The problem is the media and political “glamorization” of shootings. For some, mentally disturbed, or otherwise feeling left out, even horrendous publicity that puts their names in lights is desired recognition when it is broadcast 24/7 for weeks on end.
I say up-arm anyone and everyone who is eligible under state laws, CCW and go. These pussies attack the soft underbelly of society. Make it hard. Meet strike for strike and these wanna be’s will die at the door...
