A big reason why the semias are so popular is that the US is still a country where owning a gun is the primary way to protect yourself from gun violence.
That’s not necessarily true elsewhere, and the United States is far from perfect when it comes to gun violence — and gun ownership itself.
But there are many places where owning guns is the only way to stop crime.
The country’s gun ownership rate is about one-fifth of the average for the OECD, and one-third of the US population, according to the US Bureau of Justice Statistics.
But the US has some of the most restrictive gun laws in the world.
Here’s a look at what those laws look like and how they might change under President Donald Trump.
Gun owners in the US have access to a wide variety of guns, from assault rifles and semi-automatic pistols to high-capacity magazines, so the restrictions vary from state to state.
States with stricter gun laws tend to have more gun deaths, so gun owners in those states are more likely to carry a gun.
There’s also a lot of variation in the types of guns people are allowed to buy.
In states that ban high-powered rifles like the AR-15, which is used by the gunman in the San Bernardino shooting, for example, those are the guns most likely to be used by criminals.
In a study of California residents’ gun ownership habits, for instance, nearly one-fourth of the residents reported having owned a firearm in the past 12 months, including a majority of law-abiding gun owners.
“You can’t make guns in America the same way you can make cars, airplanes, or boats,” says Paul Bressler, a gun-control advocate at the Brennan Center for Justice.
The US is also an expensive place to own a gun, at least in the short term.
The average cost of a gun in the United Kingdom, where owning one costs about $2,000, is about twice as high as in the U.S., according to a report by the think tank GunPolicy.org.
That means that owning a semiauto handgun in the UK would cost you around $2.5 million more per year than in the USA.
While guns are often sold for much cheaper than they are in the states they are sold in, the United Nations estimates that gun crime is at its highest level since 2000, with nearly 8,000 deaths annually, and more than 50,000 gun-related deaths.
So while buying a gun can be a good choice if you don’t mind paying more for it, it’s not the only option.
If you want to protect your loved ones from gun crime, you can always buy a semi-automatic gun that’s more effective, quieter, and less prone to accidental discharge.
A few gun-safety measures that have been adopted in the country under President Obama include universal background checks, limiting gun sales to private parties, and requiring gun sellers to install locks and other security measures to prevent unauthorized access.
All of those restrictions have been controversial in some places, and it’s unclear whether the laws will actually reduce gun violence or merely increase it.
Gun-control advocates have pointed to a study by the University of California, San Diego, that found that banning high-caliber weapons would increase the risk of firearm injuries, including accidental deaths, among teens.
In the US, the National Rifle Association has been lobbying for gun control legislation, but the NRA has generally declined to endorse specific legislation.
So far, there hasn’t been much pushback from gun-rights groups or politicians, says Jennifer Gibson, a professor at New York University who studies violence against women.
And gun control measures have largely been passed without public debate or debate in Congress.
In some cases, like the National Firearms Act of 1986, the NRA supported legislation that would have expanded background checks and gun-ownership restrictions.
But gun-law reformers say they are more optimistic that politicians will act to curb gun violence than they were last year.
“There’s a growing recognition that guns have a significant role in crime, and that we need to get rid of these weapons,” says John Feinblatt, a former top official in the Obama administration and a senior policy adviser for the National Shooting Sports Foundation, a trade group that represents manufacturers and dealers of firearms.
And the NRA and other groups, like Americans for Responsible Solutions, a lobbying group focused on gun-policy issues, have worked to increase awareness of the issue, especially in states that voted for Trump.
“It’s just been a lot easier for us to get on the radio, talk about the issue and make a big difference,” says Feinblatts.
In many places, though, there are gun-violence prevention efforts that are far more expensive.
In Arizona, the state with the second-highest gun-death rate in the nation, gun-free zones are not available to the public.
That makes it difficult
