The problem with banning weapons basically boils down to “weapons already exist.”
Bad actors have them and will not give them up voluntarily. It’s very simple to say “they should be banned,” but short of Star Trek-level scanner technology, it’s impossible to find all of them. If everyone else gives them up, then the bad actors essentially run the show.
If we were somehow able to ban and dispose of all existing weapons, another problem presents itself: namely, weapons can be created or improvised from other items. 3D printers can make guns (yes, really), knives are a standard and critical kitchen tool, baseball bats are recreational equipment, even pencils have been used as deadly weapons. “Banning weapons” requires banning essentially anything heavier or sharper than a balloon; and even then, you could suffocate someone with it.
Imagining that we were somehow able to do away with all things that could be weapons, as well, we are faced with a third problem: that during the time that we’re making this change, law-abiding countries and citizens will be disarmed, while criminal elements will retain their weapons.
Conservatives and gun nuts (particularly in the US) deploy this weapon on an individual level (“when guns are criminal, only criminals will have guns”), but it’s much more salient on a governmental level: to wit, when you are invaded by another country, you’re going to have to have your own weapons to counter theirs. And the promise of police (while debatably realized) is that they wield weapons to protect unarmed individuals from violence carried out by criminals with weapons.
Some people on Reddit were talking about how only dictators would want to disarm people.
They’re wrong that only dictators want to disarm people, but they are right that dictators have a vested interest in banning weapons. A resistance is a lot harder to put down when that resistance is armed.
The reality, though, is that this particular talking point was encouraged by the American NRA (National Rifle Association), which masquerades as an organization for firearm owners and users but is actually a professional organization of firearm manufacturers. It has spread to other countries from there.
I believe weapons should be banned
Should be? Yes. Can be, safely? Good question.
and that crime should not exist in the first place.
Everyone thinks that. That’s why we call it “crime.” It’s named that because it’s stuff we don’t want to happen, so we get together and assign a penalty to everything we don’t like and call them “laws.”
Okay, everything above is not my opinion, but reality. That’s the state of the world, and the logical outworking of the state of the world. What follows is my opinion. As you may be able to tell, I am a U.S. citizen, so my answer is based largely around that context.
We have to significantly ban and restrict and curtail weapons: sale, possession, and use. Dramatically. Especially firearms. Particularly especially military-grade weapons.
It should be essentially impossible for private citizens to own firearms, and those who are allowed to own them must provide a valid reason (“collecting” working, non-historical weapons is not a valid reason) and be subject to a background check, registration, psychological evaluation, extensive training, and mandatory safe storage requirements. They should be required to join and maintain good standing in their local National Guard or other defense organization. Individuals who currently own firearms and are unwilling or unable to comply with the new regulations must surrender their weapons or face imprisonment for the sake of public safety.
In line with that, ordinary police and private security firms should not be permitted to carry weapons more deadly than a nightstick and pepper spray; with more psychological evaluation and extensive training, perhaps a taser. Firearms should be exclusively allotted for specific use cases, such as animal deterrence in communities near wilderness areas, and perhaps SWAT teams. Qualified immunity should be abolished, and every person killed or injured by a police officer’s weapon should result in immediate suspension of the officer, pending an external audit and investigation.
All weapons and ammunition used by any private citizen, police officer, private security employee, or military personnel should be subject to strict check in/check out regulations, and should include a valid reason for checkout associated with specific training activities or a specific, single incident requiring their issue. Government employees (members of law enforcement and the military) and private security employees should be subject to mandatory bodycam activation (with the footage declassified) any time weapons are checked out.
That is what can be done now, safely, without unduly endangering individuals. We know that it can be done, now, safely, because many other countries have done it.
AOSP is still open-source. If they do, it can be forked.
