YOU!
I'll add to this: Two things that I see missing from this picture (prior to the rampage) is guns and God.
If our children are our most precious resource (and they are) then why the Hell are we not protecting them as such? We are living in a society where we see the results of decades of no limit/moral relativism teachings has produced. None of us are surprised (at least none of us that know what turns savages into savages) and we have no real choice but to ride out this part of our Country's history while trying to turn back to societal mores that reflect what they used to be. Until the day arrives where people act like civilized human beings and not ego-maniacal animals, we had best be prepared to make these trogs assume room temperature should they ever cross our paths. That includes safeguarding our children with more than good intentions.
Creating "gun free zones" does nothing to stop criminals, it only emboldens them. I have yet to see one area of restrictive gun control do anything other than corral the sheep for fleecing. What these liberal shitbags have done is set up areas where the maximum amount of damage can be done in the minimum amount of time. CT is not exactly known for its lax gun laws so according to liberal "logic", this type of event never should have happened. That they don't see this is really no mystery, these aren't exactly "smart" people to begin with. If there is one thing we could point to that can be hung around their greasy necks, it would be the free fire zones they create in the areas they control.
Kicking God out of school did not happen in a vacuum. Whenever there is an area where God is denied, you can expect chaos, darkness, tyranny, mayhem, and death to follow without fail. Every place where God was denied, people suffered. I'm not saying that bringing the Lord's Prayer back to school day routine is going to solve everything, but it sure wouldn't hurt to return the damn schools to some semblance of morals and standards that they used to have.
Liberals are responsible for this tragedy - they own it 110%. Don't you guys think it's high time we made sure they did?
