the obvious solution from a non-american perspective is just ban guns.
however i realise that won't happen.
what about some kind of wireless device built in to all guns so they won't work within range of a certain signal. so for instance, schools, playgrounds, shops, churches, individual homes could all be working gun free. i'm sure thats quite feasable with current technology. it would mean everyone giving up or having old weaponry modified, but i reckon it could work
While I appreciate the attempt at finding an innovative solution, that sounds so incredibly easy to bypass and to cause problems that I don't think it would be feasible even if it could clear the legal hurdles.
In order to be fitted to an existing gun, you would need something that will interrupt the mechanical operation of the gun. That would require it to fit externally (like a trigger lock) without being too bulky or internally where space is at a premium. That would place it near the surface and easily accessible for those who would wish to disable the electronics that would make such a system possible. There's already a huge market for making legal and illegal modifications to firearms, and exploiting systems like this would be a boon for that industry.
Likewise, if it were built in to a new gun, those who would choose to buy one and not just get an old black market non-electronic version wouldn't want to have to replace the whole gun each time a chip suffered damaged (which is a distinct possibility in a weapon with an internal explosion going off beside the chip every time you practice), so it's placement would likely be somewhere where a manufacturer could easily replace it, and again that would make it accessible to those who would want to disable it.
I could see wireless jammers or electronic signal shielding being sold illegally to block such signals, or conversely, I could see criminals buying the wireless transmitters themselves in order to disable the weapons of people they plan on robbing or kidnapping or killing in areas not covered by the transmitters.
Also, while I'm no advocate of arming teachers or having armed guards in every school like the NRA, it's also true that (rarely) people are saved or the gunman is stopped by an armed citizen with a firearm. So while I would not be in favor of increasing the number of firearms present in a given area as a preventative measure against mass shootings, because that's counter-productive, I also would not want to completely limit the possibility of someone in the area who happens to be armed intervening in an emergency. At least while we still live in a country where gun ownership is so prolific.
I hope it doesn't come off like I'm just trying to shoot down your idea out of hand, because I'm not. Like I said, I do appreciate the attempt to think outside the box.
Personally, I think in order for the gun culture in America to truly change it's not going to be something that's going to be regulated out of existence (which is not to say I'm against reasonable regulations; I'm not) but rather it's going to have to be a generational shift combined with education/overcoming ignorance much like the ones we've had for smoking in the recent past and gay acceptance and gay marriage in the present (which is not saying those two things are directly comparable in any way, just that their public perception has changed rapidly for the worse and better respectively, and especially quickly in the latter case). Growing up and going to school in the 80s and 90s, it's remarkable to me seeing the amount of change on those issues that has come about as a result of education in the first place and exposure being used to combat ignorance, intolerance, disgust, and fear in the second. I hope that the perception of guns will change rapidly as well, but to where they are seen in a more negative light like cigarettes are today.
That's the point. Take away the firearms, and you automatically reduce the fatalities. You will never be able to stop meltdowns and killing spree attempts. But gun (weapon) control reduces the fatal effects dramatically. There's no reason whatsoever for a civilian to own an automatic firearm. There's also no reason for a civilian to own a sharp sword. Knifes, chainsaws, etc... are TOOLS. Guns and swords are WEAPONS. Distinction by purpose. Civilians do not need weapons of any kind. And even for certain tools you'd need a proper license before you're allowed to own one (chainsaws, for instance. Why the fuck do you need one when you're not a lumberjack?). A hunter needs a rifle for sure. That becomes his tool to do his job. But he does certainly not need an M16 or G36. When will people finally get that?
This is taking things to absurd levels. You can use chainsaws in your yard to cut up overgrown trees and branches. Not everyone needs to hire a contractor to do everything for them. How many chainsaw rampages have their been outside of horror movies set in Texas and futuristic gameshow Schwarzenegger films? Certainly not enough to justify banning them unless it's specifically part of your work requirements.
