This morning, an unhinged gunman shot and killed WDBJ reporter Alison Parker and cameraman Adam Ward while they were filming a segment in Virginia. It is the latest in a quickening drumbeat of unconscionable shootings, each more shocking and horrifying than the last.

As outraged as we are today, is there anything those of us here in New York City can do to try to forestall the next one? New York has some of the strictest gun laws in the country, but, seeing as we're strapped to the whims of the rest of the nation, we need to throw our collective weight toward a cohesive solution to ensure that guns are removed from the hands of all civilians.

New York State's current fight is safe gun storage, said Leah Barrett, the executive director of New Yorkers Against Gun Violence, which would not only protect children, but would also curb the number of guns stolen from homes or cars, a common occurrence that often results in weapons turning up in illegal gun markets. The Safe Weapon Storage Act was introduced to the state Senate in February, and you can message state Senate and Assembly representatives, as well as sign an online petition in support of the law here.

"There are just so many guns, and they’re so poorly regulated, that it’s not surprising these things continue to happen," Barrett said in an interview.

On the national scale, universal background checks are still not required before a gun purchase is made—current law only mandates checks to be made for guns sold through licensed firearm dealers, which comprise just 60 percent of U.S. gun sales. Between gun shows, the internet and private sales, it is, as Barrett puts it, "ridiculously easy to get your hands on a gun." And anyway, in most mass shootings, killers obtained their weapons legally.

The mindset of the NRA is that criminals will find ways getting their hands on weapons, "no matter what."

"With that logic, why have any laws for anything at all—why have a law against murder, why have a law against stealing," Barrett said.

Earlier this month, actor and comedian Amy Schumer joined her cousin Senator Chuck Schumer to call for gun control in the wake of America's rash of mass shootings. Their proposal includes to-be-introduced legislation to reward states for supplying information on people to background check databases, and penalizing those that don't; pushing the Justice Department to study states' protocol for involuntary psychiatric commitment; and seeking additional federal funding for mental-health and substance abuse programs. Schumer the legislator also pledged to try to close loopholes that make gun-buying as easy as picking up a couple of kids' books at a stoop sale.

Most advocacy websites have "take action" pages—like here—where you can write messages to legislators pushing for gun control. More importantly, Lori Haas, the Virginia director for the Coalition to Stop Gun Violence, says it's time to stop voting for elected officials who are anything less than strident when it comes to gun control.

"We have elected officials who voted against background checks, we have elected officials who are aligned with the gun lobby," she said. "We have elected leaders that care more about the gun lobby than they do about the safety of citizens." Stop voting for these people.

"People are getting sick of it, but I’m not sure they’re sick enough to actually stand up and demand change," said Barrett. And yet: Guns kill approximately 88 people in the U.S. each day, and kill and wound more than 100,00 Americans each year. According to a 2007 report from the Switzerland-based Small Arms Survey, the U.S. makes up less than 5 percent of the world's population, but has between 35 and 50 percent of the world's civilian-owned guns.

"People can’t just throw up their hands and say 'Oh this is going to continue, we can’t do anything about it.' No social ill is ever solved that way," Barrett said.

"Join something. Put your energy somewhere, if this problem really does touch you, and you are fed up, like so many people seem to be. But do not give up."
