I have read most of the posts and many of the responses. The perpetrator was full blown insane, that is obvious, someone, a friend or friends or family knew this before it happened or suspected it before he flipped and performed his evil project. It is obvious he had this planned for a while, who knows how long but he was committed to execute his sick and twisted project no matter the outcome.
This horrible event has nothing to do with gun laws, absolutely nothing, where there is a will there is a way.
This is a symptom of the broad cultural change that began 20 maybe 25 years ago. We have allowed this culture change to manifest to the point, that now we have many individuals who don't have any kind of a family life or an anchor to family or moral guidance in the form of religion that distinguishes right from wrong, it is no longer a commonsense thing and life is almost meaningless in value to a certain percentage of our population. The lack of close family ties, love and discipline is the root cause of this evil.
Just think, less than 10 years ago, being gay was not that cool in most circles, now we have legalized same sex marriage, a guy that went through hormone therapy and got breast implants and was nominated as woman of the year! Thats nuts if anything ever was.
This group of cultural misfits are the unknown insane among us, that we don't notice, they are invisible until they do something horrible, and they do it to become visible. No one listened to them in the past, no one really cared for them in the past I'd almost bet he was an outsider in almost all social situations. Spends most of his time on the Social Media platforms being brain washed to radical ideas, no real friends, alone and confused about life and his plight in it.
He was ready to act out in his twisted sick way and he knew the outcome before he stepped in that school, and he just didn't care just so long as he inflicted as much pain and suffering as he could to the most innocent among us in the short amount of time that he had.
This is not the last time this will happen, there are a lot more young people out there that are in the same dire situation this nut job was in, they are product of our new cultural norms.
If we, as a society don't try to make serious changes as to accountability for individual decisions that injure, kill or destroy other peoples lives and property soon, I see full blown anarchy and violence like we have never seen before.
I live just north of Houston, TX, its already here, let me tell you this area is a war zone, I can't tell you how many kids have been killed or wounded in the last few months, but it is significant. Someone gets killed everyday in a road rage shooting, the apartment complexes have 2 or 3 murders every night, we've had 9 cops killed or wounded since the 1st of January, these insane criminals will shot and kill you over a 20 dollar bill and the Black on Black crime is nuts they are killing as many of each other as they can it seems.
God bless us all and may sanity make a comeback soon, but I fear that will not be the case.
