Doctors on Guns

The American College of Physicians is recommending solutions to what it says,"continues to be a public health crisis," and "Firearm violence continues to be a public health crisis in the United States that requires the nation's immediate attention."  You would never know that murder rates are now below 1965 rates.  To quote Snopes:

FBI statistics show, in fact, that the 2015 murder rate was among the lowest of the past 47 years, and indeed the lowest of any year between 1965 and 2009.

Their requests include:

ACP supports strengthening and enforcing state and federal laws to prohibit convicted domestic violence offenders from purchasing or possessing firearms. Domestic violence offenders include dating partners, cohabitants, stalkers, and those who victimize a family member other than a partner or child. ACP supports federal legislation to require that such domestic violence offenders be reported to the National Instant Criminal Background Check System. 

Individuals convicted of a domestic violence misdemeanor should be prohibited from purchasing and possessing firearms based on existing federal law. The federal government should encourage states and localities to create a process for these individuals to surrender firearms they already possess. 

Too late! 
Already federal law.  To quote ATF:

Misdemeanor Crime of Domestic Violence

Does the prohibition on receipt or possession of firearms and ammunition apply if the person was convicted of an MCDV prior to the enactment of 18 U.S.C. 922(g)(9) on September 30, 1996?

Yes.

And:

Individuals subject to domestic violence restraining orders, including temporary orders, should be prohibited from purchasing and possessing firearms and be required to surrender their firearms for the duration of the order.

From FindLaw.com:

Both federal and state laws prohibit violent domestic offenders from owning or having contact with firearms, as firearms are often used to threaten, injure, and even kill the victims of domestic violence.  

Also requested:

The College supports a ban on firearms that cannot be detected by metal detectors or standard security screening devices, including but not limited to 3D-printed firearms. 

Way too late.   18 USC 922(p) is the Undetectable Firearms Act of 1988.

It shall be unlawful for any person to manufacture, import, sell, ship, deliver, possess, transfer, or receive any firearm - (A) that, after removal of grips, stocks, and magazines, is not as detectable as the Security Exemplar, by walk-through metal detectors calibrated and operated to detect the Security Exemplar; or (B) any major component of which, when subjected to inspection by the types of x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the component. Barium sulfate or other compounds may be used in the fabrication of the component.

More evidence of their ignorance:

The College favors strong penalties and criminal prosecution for those who sell firearms illegally and those who legally purchase firearms for those who are banned from possessing them (“straw purchases”).

Straw purchases are already illegal.

The Bureau of Alcohol, Tobacco, Firearms and Explosives has partnered with the National Shooting Sports Foundation (NSSF) — the trade association for the firearms industry — in designing an educational program to assist firearm retailers in the detection and possible deterrence of “straw purchases,” the illegal purchase of a firearm by one person for another.

How seriously can you take requests for laws that are already in place?
