More of the whole slippery slope. Each new shooting we ban one more gun, or one more gun accessory. Fox News is told in court they are not real news cause of all the opinion stuff. The way other news sites are like CNN these days, I can see others lose that. Trump mentions a gov't run news station to prevent bias. Protesters constantly preventing people they don't agree with from speaking at public places like universities. Mentions of banning certain words due to their hatefulness. ECT.
In say 100 years, is it unfathomable to imagine a US that all weapons are banned, all news is government run and you can be jailed for speaking out in public on something people don't agree with?
But lets talk only this one case. But as for your bolded. Lets say their are better rules for gun ownership. Tell me how that would have prevented this event? The only people surprised by the school shooting and didn't see it coming where his guardians who are coincidentally trying to now get his $800,000.00 inheritance. At least two people contacted the FBI and warned them about this person doing a school shooting. The police had been to his house like 30+ times. He was expelled from school. He had photos of animals he killed and such on facebook. What did anyone do to prevent him from his mass murder? NOTHING. Whether he used a gun or not, he would have done something and it was apparent to everyone, except the people trying to get his money. Yet what was done? NOTHING.
Can you structure your argument more clearly? I don't see the point you're trying to make.
I have two points.
1. This school schooting was 100% the fault of the police, FBI, ect for not doing anything. They all seemed to know this kid was messed up and trouble and yet nothing was done. His method of killing is not the problem, the problem was knowing a killing would happen and ignoring it.
2. The slippery slope is what a slippery slope always is. Think of DLC/microtransactions. In the start they were little things and slowly it has become worse and worse. Even when you have huge outcry like EA battlefront, they still sell millions and micros are not going away. Same with laws. Think of gun laws. Lets say their is a shooting and they ban automatic weapons. Then next shooting they ban silencers. Then next shooting they ban semi-auto's. then next shooting they ban shotguns, ect. It's a common thing to do. you know you can't ban something or implement something all at once, so you take baby steps.
It's the classic situation where you don't care until they finally come after you. I'm sure you would laugh, scoff or get angry whenever someone comes out and tries to blame video games for violence. But that is what I'm talking about. They ban guns finally. You don't care cause you don't have any guns. Violence still persists, so they ban knives. Again you don't care cause you don't have knives. Violence still persists, so they then ban violence on tv, movies and video games. Now you care and are complaining that they are coming after you and that video game and movies don't cause violence.
BTW, I do blame video games and movies more than guns for violence. Guns, bombs or weapons of any kind are just tools. It's a mental thing that makes one do violence. is that video games or movies? Sure for some. It could also be NRA meetings, church, parents, friends influence, facebook post, movie, book, ect. All those things and more influence a persons thinking, mentality, character, ect. A gun is just a tool. An effective tool, but a tool non the less. Think of Nuclear energy. It can be used to power a city, or it can be used to reduce it to ashes. It all depends on the person who is using it's motives. The splitting of atoms itself is not the enemy.
