Guns: how much longer will it take ....

Just trying to pick you guys' brain about what guns are the most efficient in terms of killing a large number of children in a short time.

Just assume the children are Italian or Palestinian, if that makes it easier for you to answer the question.

The focus should be on how to reduce the frequency and lethality of mass murders, in schools or otherwise. Hence my question.

In support of its motion for summary judgment, the State
proffered extensive uncontroverted evidence demonstrating that
the assault weapons outlawed by the FSA are exceptionally lethal
weapons of war.3

the AR-15
— is simply the semiautomatic version of the M16 rifle used by
our military and others around the world. Accord Staples v.
United States, 511 U.S. 600, 603 (1994) (observing that “[t]he
AR-15 is the civilian version of the military’s M-16 rifle, and
is, unless modified, a semiautomatic weapon”).

In combat-style testing
conducted in 1959, it was “discovered that a 7- or even 5-man
squad armed with AR-15s could do as well or better in hit-andkill
potential . . . than the traditional 11-man squad armed
with M14 rifles,” which were the heavier selective-fire rifles
then used by soldiers in the Army. See J.A. 930.4 Subsequent
field testing in Vietnam, in 1962, revealed the AR-15 “to be a
very lethal combat weapon” that was “well-liked . . . for its
size and light recoil.” Id. at 968. Reports from that testing
indicated that “the very high-velocity AR-15 projectiles” had
caused “[a]mputations of limbs, massive body wounds, and
decapitations.” Id.

The difference between the fully automatic and
semiautomatic versions of those firearms is slight. That is,
the automatic firing of all the ammunition in a large-capacity
thirty-round magazine takes about two seconds, whereas a
semiautomatic rifle can empty the same magazine in as little as
five seconds. See, e.g., J.A. 1120 (“[S]emiautomatic weapons
can be fired at rates of 300 to 500 rounds per minute, making
them virtually indistinguishable in practical effect from
machineguns.”). Moreover, soldiers and police officers are
often advised to choose and use semiautomatic fire, because it
is more accurate and lethal than automatic fire in many combat
and law enforcement situations.
The AR-15, semiautomatic AK-47, and other assault weapons
banned by the FSA have a number of features designed to achieve
their principal purpose — “killing or disabling the enemy” on
the battlefield. S

Several manufacturers of the banned assault weapons, in
advertising them to the civilian market, tout their products’
battlefield prowess. Colt’s Manufacturing Company boasts that
its AR-15 rifles are manufactured “based on the same military
standards and specifications as the United States issue Colt M16
rifle and M4 carbine.” See J.A. 1693. Bushmaster describes its
Adaptive Combat Rifle as “the ultimate military combat weapons
system” that is “built specifically for law enforcement and
tactical markets.” Id. at 1697.
In short, like their fully automatic counterparts, the
banned assault weapons “are firearms designed for the
battlefield, for the soldier to be able to shoot a large number
of rounds across a battlefield at a high rate of speed.” See
J.A. 206. Their design results in “a capability for lethality —
more wounds, more serious, in more victims — far beyond that of
other firearms in general, including other semiautomatic guns.”

The original AR-15, designed in 1959, became the M16 after Colt acquired the manufacturing rights in 1962 and it became the main weapon of our troops in the Vietnam conflict.

One needs only look at uncontroverted facts that exist in court rulings.

Your question is idiotic. Do you really want to be seen as this stupid by other gun owners?

As usual, you can't refute the facts so you just claim it has no meaning.

Do you also argue that DC can ban hand guns because the Heller ruling is only trivia?

Why would the manufacturer claim it used the same specifications as the M-16 if they were no more alike than the M-16 is to a Mossberg Plinkster?

Can you figure out why the AR-15 is more like an M-16 than other rifles when they share the same repair manual?

But even when the work was done, rather than accept it you are making excuses and trying to deflect from what the statistics actually say. Your response below is riddled with math and factual errors. I will include my response with red.

Today the Ninth Circuit Court of Appeals upheld a federal district count injunction against a California law to confiscate firearms magazines that hold over 10 rounds. The Ninth Circuit's 2-1 opinion is here, and the dissent is here. My analysis of the 2017 district court opinion is here.

until they get to the SCOTUS where they will lose.
