OK, John. Just what exactly is your proposal?
I did not see my school on your list. I was in a school shooting and I was one targeted by the shooter. Shooter had a list of kids he wanted to "prove something" to and fortunately for me most of the other 9th graders on that same list were at 1st lunch period and I was in Algebra class on the other side of the school when the 14 year old shooter came in and started hunting. Most fortune for all of us there that day the principal saw the shooter before anything happened and confronted him in the hallway. The principal asked the kid where he was going with that rifle. The principal told the kid to hand over his gun. The kid said nothing but pointed the gun at the principal and shot him in the chest, killing the principal. (Witnessed by several of the office personnel.) The principal was in his early 30s and left behind his wife, several children and a baby on the way. Said principal was also a US Marine and no way in hell was he going to let anything happen to his students. The bravest of men he was. And he proved it.
We who were there and the official investigation figured the actions of the principal saved many lives that day. Although more students and teachers were shot that day and thankfully no more killed, the shooter running into the principal forcing the shooter out of his plan derailed the shooter and he panicked at that point, making his way through the school towards the lunchroom but never achieving it, instead finding an exit and running from the school. The shooter did shoot his way from the principal's office (the location of the principal's murder) taking shots at whomever he encountered in the hallways, wounding at least 2 other teachers and 2 students before leaving the building, where he ran through a field behind the school. He was found by police helicopter and arrested. Being 14 at the time the law had to charge him as a juvenile and he was released from prison at age 21.
The shooter had 2 guns. He took them from his dad's gunsafe. He was able to do this as the parents were not home when the kid began his actions that day. (Kid had stayed home, planning and arrived at school just before lunch, possibly in hopes of catching all students in passing period.) There is much more to the story but the details are not needed here.
We grieved. We were shocked, angry, perplexed, horrified; our young minds tainted with the ugliness that can come from a disturbed mind. Those memories never fade.
We knew the kid. We knew he had issues of which I will not detail here. We discussed everything. We analyzed every action leading up to the shooter's breaking point. We over analyzed the school, the students, the culture, the hows and whys. You know what was not discussed? You know what didn't matter? The guns used. Why? Because that is disingenuous to the conversation. The true focus was everywhere else, because that is what mattered. We placed blame on the person. He was solely responsible for this. His actions. Not anything else.
You know what? This kid's profile was the exactly same as all the other disturbed individuals who have done this since then. Physical or mental abuse, lack of spirituality and morals, a fragile psyche, perceived societal abuse, who knows exactly what and how all his surrounding stimuli was processed and led him to this violence. It wasn't the inanimate objects in his dad's gunsafe though.
John, you posted a long list of schools that I assume have experienced some kind of (I hate to use this term...) "gun violence?". Is it your contention that a particular style of weapon was used in each one of these? Without spending vast amounts of time digging through all the particular details of each you've listed to verify this, I'd have to say if this is your point, you've erred. And the argument to ban something inanimate misses the point of all this carnage entirely.
Now for the media's drive to enact more gun control, they will never fail to use the red herring of the gun itself. Interesting to note, the Santa Fe HS shooting in 2018 quickly became a non media issue as soon as the media discovered the shooter used a pump shotgun to murder 10 people in school. Hmm. The gun did not fit their narrative. I'd also submit that the mass shooting at Pulse gay nightclub in Florida where 49 people were murdered became a non story as soon as the media discovered the shooter was a gay muslim. Again we see the media's narrative could not be maintained because the media only care about the story if all the details fit their political agenda. How's that for BS? People die and only half truths are told. So much for reliable journalism these days.
If you think more laws are the answer, that is fallacy. Murder is already unlawful yet that doesn't stop murder. Legislating against lawfully owned firearms does not solve anything.
Again what exactly are you proposing?
