As the end of 2013 approaches, the Washington Examiner is taking a look back at the biggest stories and issues of the year. Today, it’s the contentious gun-control debate.
Guns entered 2013 on the political forefront after the Sandy Hook Elementary School shooting in December 2012, and President Obama looked to tighten existing laws early in the year. He struggled to compel Congress to act, but firearms issues resurfaced in July after George Zimmerman was found not guilty in Trayvon Martin’s death and in September after a workplace shooting left 12 dead at the Washington Navy Yard.
Here are some of the top Examiner stories of 2013 on gun control:

By Tim Mak, Nov. 29
As the 25-year-old law banning the manufacture of guns not easily screened by metal detectors came up for renewal in December, the rise of 3-D printing technology brought new questions about gun control to the Capitol.
[New York Democratic Sen. Chuck] Schumer has warned of the “scary pace” of plastic gun development, and says that anyone with an Internet connection and “”a little over $1,000″” can now produce an undetectable plastic gun.
“We are looking at a world in which anyone with a little bit of cash can bring an undetectable gun, that can fire multiple bullets, anywhere — including planes, government buildings, sporting events, and schools,” Schumer said.”

“I’m asking you to join me today, six months after that horrible day, to keep this fight going,” Lafferty said in the email.
“Take action for my mom, Dawn, and the 25 other people who we lost in December.” ”
