Why don't they just ban crazy people? Or murderers?
Say hello to increased Red Flag laws then? Just another cliche. Not to support gun bans but the rationale is that firearms make it easy to commit multiple killings. Thus we give a murderer or crazy person a powerful instrumentality. Yes, they could use cars or make bombs but guns make it easier to do.
Technically, violence prediction is very, very iffy if you read the professional literature. The only things that might predict just a little for a rampage are:
1. Past history of violence
2. Making overt threats
3. Having a stockpile of weapons, recently acquired and without a seemingly sensible usage for hunting, collecting or competition. Beyond what one would think would be necessary for personal or home defense.
So tell me how to ban crazy people? There's not a blood test for such. Crazy is bad term, you need specific diagnostic criteria. Want to use a statistical definition - well, you have lots of guns. Thus you are way outside the mean. You're crazy - let's go get them.
Now, let's ban smart phones or cars or draino. They kill people - again a useless cliche for most arguments. The gun is a personalized threat against you. It's core purpose is violence (sporting uses are a side effect and practice for the weapons usage). The threat of aggression against you is seen as more potent that the side effect of another item whose core usage is not violence. Why did we go to war after 9/11? Cell phones kill more. It is because someone attacking you is different from a misuse of a normal, everyday item.
Again, you need to rationalize why the public needs to have instruments of lethal force or you have lost the argument.
Ban crazy people, phones, God gave us the right, etc. - not going to work in convincing someone that we have or need instruments of lethal force. The Canadians, the UK, Australia - didn't buy the sports reason. Some countries may buy into the RKBA, those that do in Europe have problems with the EU. Switzerland (gun heaven?) is starting to follow EU guidelines. Czechs are fighting them - or some of the populace are.
I guess I am ranting because when I see just a string of cliches, I see a loss.
The Canadians obviously for the most part do not accept that this misuse is countered by the greater good of having arms for self-defense or the defense against tyranny.
I note that in the USA - the latter is not a major part of our gun debates anymore. It is mocked by both pro and anti gun speakers for the most part.
Many democracies do not think that the populace will ever need to defend against tyranny.
