Simple. Publish the names and addresses of everyone associated with this publication. Also advertise that each of those addresses are Gun Free Zones.
Problem solved.
You don't bring a knife to a gun fight.
That's being done.. with the predictable whining from the news people about the invasion of privacy.. 
Tough sht. Turnabout is fair play. Oh wait .... they're the special "tolerant" people who are "serving the public", "making the world a better place" and who have a more enlightened view from on high than we peons.
To wit:
"... Frank Sesno, a former CNN reporter and Washington bureau chief who is now director of George Washington University’s School of Media and Public Affairs, said recently there should be a “media agenda” on guns to push the issue until government action becomes a reality. “The media themselves have a huge opportunity and power and responsibility to channel this,” Sesno told CNN’s Howard Kurtz."
However ...
"In a discussion about gun control, host David Gregory
brandished a 30-round magazine purportedly for an AR-15 or similar “assault rifle.” The discussion took place on December 23, during the broadcast of NBC’s Sunday morning political talk show.
Washington D.C.’s gun laws, however, state that even possessing such a device is a violation. Meet the Press is filmed at NBC’s D.C. studios…
Breitbart contacted the office of the police chief and asked if there were any plans to look into this apparent violation of the District’s gun laws. In response, Chief Lanier replied, “Yes, we are investigating the incident to determine if the magazine was in fact real.”"
That "brandish" is courtesy of Allapaininmyazz, nevertheless, Gregory is so ignorant he displayed the banned magazine on the air. Expect any substantial action against him by the "authorities"? Nah.
