Also, like most problems in society, I expect there will be a direct link to teachers unions.
But we all know that the "problem" presented depends on the perp. If it was a white guy, it would be all "white supremacy!!!" but it sounds like he's hispanic so it's "gun control!!!!"
If it turns out the guns he used were already illegal it will be ... erm, what exactly? I forget what the stock response is in that case. Make them more illegal?
When do we talk about societal problems, over prescribing of drugs on kids, the general promotion of constant rage and anger by the left for whatever distraction they want people to focus on and the constant overbearing government control.
Just wondering.
