This is a semi-automatic weapon.
It’s legal, and it’s one of the guns
used to kill 58 people at a concert in Las Vegas.
Normally, these guns can shoot about 30 rounds in ten seconds.
But the guns in the Vegas shooting were modified to shoot
nearly as fast as an illegal automatic weapon
About 90 shots in 10 seconds.
Automatic weapons can fire 98 shots in 7 seconds with a single pull of the trigger
and since 1986, it’s been illegal to own one in the United States.
So how did the Las Vegas shooter manage to nearly replicate the destruction of a gun
that’s been illegal for more than 30 years?
Mass shootings almost always involve these semi-automatic weapons
which is why they’re so deadly
These semi-automatic weapons fire much more quickly than
the kinds of firearms that have been around
for most of American history.
Shooters used semi-automatics in the Virginia Tech
Ft. Hood, Aurora,
Sandy Hook, San Bernardino,
And Orlando massacres.
Most of these shooters also used high-capacity magazines, which make semi-automatics even
more deadly by reducing the time spent reloading.
But the Las Vegas shooting was different.
The semi-automatic weapon the shooter used had been modified to be even more deadly,
using a $99 add-on called a bump stock
which uses the gun’s recoil power to automatically put pressure on the trigger.
This seems hard to square with the text of the 1986 law, signed by President Reagan,
里根：“我确信 AK-47 机关枪不是运动型的武器
Reagan: “I do believe that an AK-47, a machine gun, is not a sporting weapon, or needed for
defense of the home” Which not only made it “unlawful for any
person to transfer or possess a machine gun,” it also outlawed “any part designed and
intended solely and exclusively, or combination of parts designed and intended,
for use in converting a weapon into a machine gun.”
But a 2010 letter from the Bureau of Alcohol, Tobacco, and Firearms
posed on the website for one bump stock manufacturer
says that because the product attaches to the exterior
and doesn’t have any mechanical parts, it’s legal.
In 2013, a few months after the Sandy Hook shooting
Senator Diane Fienstein proposed a bill
that would’ve ban bump stocks.
But the bill never came up for a vote.
