I'm Australian, I support gun laws like we have here.
Firearms-Control Legislation and Policy: Australia I can't imagine the US government buying back firearms like they did here. The statistics show we had a great decrease in gun related deaths and injuries after stricter laws were introduced. I don't know how well that would go down in the US though, because we never had the same gun culture to begin with. American's tend to feel they not only have a right to be armed but should be, correct? Do you have laws in place for automatic and semi-automatic rifles?
America is an immigrant nation. My ancestors arrived from Ireland and Scotland in the late 19th and early 20th century, stayed in NYC. This "gun culture" you imagine was not part of the lives of European immigrants who settled in NY, Boston, Washington, D.C., Chicago. The population of the U.S. was 76 million in 1900 and is now 330 million.
On the west coast, immigrants came from China and Japan, and later, from Mexico. The Asian immigrants also stayed in cities.
None of the immigrant countries I mentioned had "gun cultures." Most of these later immigrants who stayed on the coasts never even knew about this "gun culture."
Although we apparently have 120 guns for every person, they are only owned by 30% of Americans. Probably most of the 70% who don't own guns are people who, like me, had absolutely no desire to ever own a gun or live in a home that had guns. Do they feel that Americans have the right to bear arms or should be? I have no idea. I always thought the second amendment was some sort of archaic throwback to the eighteenth century, completely irrelevant and unnecessary.
And so there you have it. After the industrial revolution, the huge numbers of immigrants who came to the United States arrived and settled in cities where they were never exposed to "gun culture," and whose lives were never diminished by not having been exposed to it. And even now, 70% of Americans don't own guns. In NY, my home state, it is under 15%. Where I live now (sigh) it is over 50%, but among my friends here, it is 0%.
In 1980, the NRA changed from an organization of mostly peaceable hunters. They launched an aggressive and well-funded campaign to vastly increase a "gun culture" that didn't exist in much of America. They funded chairs in law schools, like the Federalist Society does, to train lawyers who would promote gun rights at every turn and eventually become judges. They also funded politicians, and still do.
And there have been gun buybacks. When I lived in St. Louis County in the 1990's, St. Louis City, which had a high crime rate, had regular gun buybacks. "Gun culture" doesn't work well in cities.
