Hate to break the news to ya, but you obviously forgot about OKC, one of the biggest attacks in history of the USA, and they used nothing more than fertilizer and gas. And what have we been seeing in places like Paris? Guys in trucks screaming Aloha Snackbar while running down dozens. Pro Tip...if a scumbag wants to kill lots of people? The Anarchist Cookbook can be downloaded in seconds and gives you the recipes to do massive damage just using the stuff found in your average kitchen. Are you gonna ban chemistry?
If you want to actually do something about school shootings? Here is 3 simple steps that would make it a LOT harder and less attractive to scumbags...1.- Give schools the same ability to push a single button and lock the place down like they have in hospitals. you'd be amazed how many schools have ancient buildings that simply cannot be locked down without some person going around with the keys. 2.- Give teachers firearms training and have them armed, look at how many teachers have given their lives protecting kids, think about how differently it could have been if the teacher had a way to defend their charges besides being a human shield. 3.- STOP GLAMORIZING THESE DOUCHEBAGS! They see their faces plastered on the news networks, stories about them for weeks, it allows any loser to get 15 minutes of fame and get tons of attention...think those same losers would be so willing to charge in if they saw the headline "needle dicked loser that was nothing but a complete failure at life proves that he should have been aborted by killing others"? Stop giving these losers positive press, let them know they won't get their name and picture plastered everywhere and the only time their shown will be with titles like "worthless' "pathetic" "impotent". There have been studies that show that these crimes go up after there is a lot of press about an attack because losers want to have the infamy the other guy got, why give it to them?
But if you think banning guns would do shit? I have a bridge you might be interested in. After all how long has it been illegal to cross the border without permission? How long has SLAVERY been illegal? According to Amnesty International thanks to our broken southern border we have thousands of slaves being brought in every year for sexual abuse and slave labor, do you honestly think getting slaves across the border is easier than getting a load of guns and ammo? We have literally tens of thousands of tons of illegal drugs being brought across our border every.single.year. you think the criminals can't just as easily bring a load of guns to go with the dope and the slaves? All the gun laws do is make sure the law abiding don't have a way to fight back, the criminals don't give a flying flipping fuck about your laws...hence why we call them criminals.
