The Supreme Court on Monday turned away an appeal by a group of gun rights advocates seeking to overturn Maryland’s ban on assault-style rifles and high-capacity magazines under the Second Amendment.
The decision, a major win for gun safety advocates, leaves in place a ruling by the Fourth Circuit U.S. Court of Appeals which ruled that the state may constitutionally prohibit sale and possession of the weapons.
The state legislation, enacted in 2013 after the Sandy Hook elementary school shooting, specifically targets the AR-15 – the most popular rifle in America with 20-30 million in circulation. They are legal in 41 of the 50 states.
Here’s a study on gun ownership vs gun deaths:

Here’s a graphic showing gun ownership by country:

As you can see, the US is almost 4 times higher than the next highest country.
And here’s a graphic showing the number of mass shootings by country:

Again, you can see that the US tops the chart by a huge margin (more than 5 times).
We can’t really compare based on just violence alone, because any country in active conflict severely skews the data. You’d have to include only countries in peacetime. But you can certainly compare based on gun violence, because the US always trends very high. Even when you include countries in active conflict, the US compares to them in gun violence. So, living in the US is similar to living in a country involved in active conflict with regard to gun violence.
