“… Meanwhile, the US will soon hit an average of 40,000 firearm-caused DEATHS per year.”
Calling BS.
The 40k deaths per year in the US is (likely) a CDC figure. Most statisticians figure that 50% of those were also suicides. So, the CDC also listed “…of the 26,030 people killed in 2021, 103 died in active shooter events…”. What does that say about total number of peeps killed firearms?!
Certainly no where close to 40k. And how many firearm deaths are due to gang & criminal activities ? That is a stat that there is zero chance of ever tracking accurately. The best they can do is … “ According to a 2019 report by the Center for Disease Control and Prevention, approximately 60% of firearm deaths in the United States are gang-related.”
And in a study by Northwestern University, “ Gun violence is tragic, but, in the majority of cases, is decidedly not random.” … “The violence largely involved only a small fraction of the city’s gang “factions,” just 6%.” So a very small organized minority is responsible for the majority of firearms deaths in the People’s Republic of Chicago.

“ There are three kinds of lies: lies, damned lies, and statistics.”
This quote has been attributed to prominent humorist Mark Twain, and British statesman Benjamin Disraeli.

There are some factual errors and erronous speculation in this text btw:
1) “Until just recently, Japanese law didn’t even prohibit them. The country’s gun control laws only prohibited firearms and other projectile-launching weapons, but not those using magnetic force” – While Japanese law doesn’t prohibit magnetic guns specifically, any type of firearm that has lethal potential has been illegal and continiuous to be illegal regardless of the new law. That is why this man was arrested – his coilgun was deemed to have lethal potential. (This still has the potential to be reversed after further investigation.)
2) “After the law changed, Japanese police started looking around online” – the new law comes into effect in March next year, so it hasn’t changed yet. Again, the man was arrested because his weapon was illegal in accordance with the already existing laws on arms with lethal capacity. When the law changes, coilguns will be illegal regardless of lethal capacity.
3) “The NHK article says that police are currently working on a campaign to get people to voluntarily give their coil guns to the police […], so there must be a significant number of them in the country.” – why must there be a significant number? It’s very common in civilised countries to enact an amnesty programme when a law like this is changed. It doesn’t say anything about the amount of coilguns around in Japan, just that Japanese lawmakers want citizens not to be entrapped by a changing law, and that Japanese police has the resources to alleviate that.
4) “[…] there are a thousand ways to build a gun, some very durable, effective, and accurate.” – absolutely. And Japan is at the forefront of many of the technologies available, and has been since the 1980s. Japan also has very strict gun laws, and an extremely low amount of gun violence. I wonder what the connection could be…

If that happened by some miracle, I would bet every dollar I own that the murder rate would not move a single percentage point.
