Whether or not somebody "needs" to do that is unimportant. What is absolutely sure is that somebody is definitely blasting your children to kingdom come. If you (personally) don't appreciate my advice on how to stop it, it's no skin off of my azz. You'll just have to bite the bullet and suck on my opinion anyway - because you can bet I'm still here saying what I want to say.
The Gov killed the kids just as they did before in OKC Murrah federal building. This school massacre was done with an AR-15 yet the weapon was found in the car. The autistic kid did not pull of the superman feat of action, the Gov did.
The way to stop the school massacres is to place armed guards to protect defenseless children. Adults elsewhere can all protect themselves. But the Gov had no interest in protecting the children and wanted a massacre for their gun control agenda to support the soon civil war with all the illegal immigrants supported by Washington DC weapons program Fast & Furious.
