do they look normal to you?
Who ever said that shooting up a school or workplace was acceptable behavior? Where did the shooters get the idea that they could go and do that? How on earth did American society degenerate into a "mass shooting a week" society?
In the old days (yes, I am a dinosaur) how many mass shootings did we have in America? Practically none. The earliest mass murder in America I could find was in September 5, 1949: "In Camden, New Jersey, 28-year-old Howard Unruh, a veteran of World War II, shoots and kills 13 people as he walks down Camden's 32nd Street." Then, we had one or two mass murders in America in the 1960's. Why do we have so many mass shootings now? I don't know. I only know that it is UNACCEPTABLE behavior.
Here's a memo for all the crazies who want to go out and shoot people: DON'T. If you are upset, or mentally ill, and want to kill someone, do everyone a favor and kill YOURSELF. That way, if you kill yourself, you will no longer have the anger and hurt and your lousy life will finally end and you will finally find peace. Plus, it'll be cheaper, you only need to buy one bullet, not a bunch of them. And turn the gun on yourself BEFORE you turn it on others. Then pull the trigger. I promise you, your agony will end.
If you are planning a mass shooting why should you kill yourself instead? Because, deep down inside, you DO care about others. Don't go shooting up a place, just shoot yourself instead, and put an end to YOUR misery. Or, better yet, if you are upset and want to go shoot a bunch of people, go see a shrink instead.
