Aurora Gunman’s Arsenal: Shotgun, Semiautomatic Rifle and, at the End, a Pistol

The three types of weapons used by the man accused of killing 12 people in a Colorado movie theater — a semiautomatic variation of the military’s M-16 rifle, a pump-action 12-gauge shotgun and at least one .40-caliber semiautomatic pistol — are among the most popular guns available in the multibillion-dollar American firearms market.

.. It appears, the police say, that James E. Holmes, the man accused in the Aurora shootings, used all three types of weapons inside the theater as well, first firing the shotgun, then using the semiautomatic rifle until its 100-round barrel magazine jammed, and finishing off with a pistol. (A second .40-caliber pistol was also found at the scene, though it was unclear whether it had been used in the theater.)

.. Many other details about the rampage also remain unclear, like whether the gunman used soft-point or full-metal-jacket ammunition, or whether any of the firearms had been modified with scopes or night-vision devices.

.. If anything, the experts said, a shotgun in that situation might have been the most lethal, since every shell can spray a half-dozen or more pellets, each capable of killing or maiming a person. Twelve-gauge shotguns often fire five shells, and sometimes more

.. “Shotguns are a very good antipersonnel weapon at close range,” said John C. Cerar, the former commander of the firearms and tactics section for the New York Police Department.

.. AR-15, marketing more than a dozen models that range in price from about $700 to $2,000.

.. it is easy to handle and can be modified in numerous ways. Some soldiers call it “a Barbie doll for men” because it has a wide range of accessories and replacement parts, including different styles of barrels, stocks, magazines and scopes.

.. The M&P15 also comes in a variety of models that fire different sizes of ammunition, from .22-caliber to .30-caliber rounds.

The rifle used in Aurora fired .223-caliber ammunition, law enforcement officials said.

.. Those rounds — similar to the ammunition used in American M-16 and M-4 rifles — are smaller than the rounds fired by Afghan insurgents wielding Kalashnikov rifles, but pack far more power than .22-caliber rounds, even though they are only a hair’s-width larger in circumference.

.. Law enforcement officials said the 12-gauge shotgun used by Mr. Holmes was a Remington 870. The gun, which can be purchased for around $400, requires the user to pump a handle underneath the barrel to chamber new cartridges after each shot.

.. The handgun was a Glock .40-caliber semiautomatic pistol, the officials said. The weapon is similar to the 9-millimeter handgun made famous in gangster films and rap music. The 9-millimeter has also been adopted by many police forces that had used .38-caliber revolvers and felt that they were being outgunned by criminals.

.. The .40-caliber Glock, versions of which sell for about $400, has become increasingly popular partly because its larger round makes it potentially more deadly than a 9-millimeter

.. Yet it has less recoil and is thus easier to handle than a .45-caliber handgun.

.. The pistols typically come with magazines capable of holding 13 to 17 cartridges.

.. Pistols are less accurate than rifles at longer distances and are widely considered harder to use because they cannot be braced against the shoulder. But in close quarters, they are plenty lethal.

Here’s a gun-control measure both sides can get behind — and it works

One policy idea, though, is being met with rare consensus by both advocates for gun control and gun rights: gun violence restraining orders (GVRO), in which law enforcement agencies, families and household members can quickly remove firearms from individuals deemed unstable or unfit to own them.

.. A court-issued GVRO compels an unfit gun owner to sell or surrender his firearms before he can do harm to himself or others while ensuring the gun owner’s right to due process.

.. A “permanent” GVRO expires after 12 months, time in which the gun owner can seek professional counseling or treatment to address underlying problems. Courts can authorize an extension of the GVRO if the gun owner remains unfit. Many Second Amendment advocates recognize that this approach strikes a good balance and that responsible gun owners should have nothing to fear.

Trumpism Is a Psychology, Not an Ideology

Trump presents an insurmountable challenge to an intellectual approach to politics because his decisions aren’t based on any coherent body of ideas.

.. Former White House chief strategist Stephen Bannon devoted considerable resources to promoting Trumpist candidates who supposedly shared President Trump’s worldview and parroted his rhetoric, including anti-globalism, economic nationalism, and crude insults of “establishment” politicians. Those schemes largely came to naught.

.. The intellectual effort to craft or divine a coherent Trumpist ideology didn’t fare much better. Just over a year ago, Julius Krein launched a new journal called American Affairs to “give the Trump movement some intellectual heft,”

.. On the left, there’s an enormous investment in the idea that Trump isn’t a break with conservatism but the apotheosis of it. This is a defensible, or at least understandable, claim if you believe conservatism has always been an intellectually vacuous bundle of racial and cultural resentments.

.. by his own admission, he doesn’t consult any serious and coherent body of ideas for his decisions. He trusts his instincts.

.. Trump has said countless times that he thinks his gut is a better guide than the brains of his advisers. He routinely argues that the presidents and policymakers who came before him were all fools and weaklings. That’s narcissism, not ideology, talking.

.. Even the “ideas” that he has championed consistently — despite countervailing evidence and expertise — are grounded not in arguments but in instincts.

He dislikes regulations because, as a businessman, they got in his way.

He dislikes trade because he has a childish, narrow understanding of what “winning” means. Even the “ideas” that he has championed consistently — despite countervailing evidence and expertise — are grounded not in arguments but in instincts. He dislikes regulations because, as a businessman, they got in his way. He dislikes trade because he has a childish, narrow understanding of what “winning” means.

.. The president’s attack on his attorney general’s conduct as “disgraceful” makes no political, legal, or ideological sense, but it is utterly predictable as an expression of Trump’s view that loyalty to Trump should trump everything else.

.. Likewise, his blather about skipping due process to “take the guns” was politically bizarre

.. And, of course, his decision to promote and protect his son-in-law, Jared Kushner, is purely psychological. Giving Kushner the responsibility to settle the Israeli-Palestinian conflict for all time seems like the premise of a sitcom

.. many of Trump’s biggest fans stick by him, mirroring Trump’s mode of thinking and discovering ever more extravagant ways to explain or rationalize the president’s behavior. (Krein’s abandonment of Trump was an exception to the rule.)

When Trump attacked Attorney General Jeff Sessions, Jerry Falwell Jr. of Liberty University tweeted his support, floating the idea that Sessions was an anti-Trump deep cover operative who endorsed Trump to undermine his presidency from within.

.. If this infection becomes a pandemic — a cult of personality — one could fairly call Trumpism a movement. But psychology would still be the best way to understand it.
