A new study by Third Way , a center-left think tank with close ties to the Obama administration, found that thousands of guns, including so-called assault weapons, are for sale online and that many prospective buyers were shopping online specifically to avoid background checks.
The study focused on Armslist.com — a popular classified site similar to Craigslist.org that facilitates private sales of firearms and ammunition based on location — and analyzed listings in 10 states where senators voted against a background-check compromise this spring.
At any given time, more than 15,000 guns were for sale in those states, according to the study, and more than 5,000 of them were semi-automatic weapons. Nearly 2,000 ads were from prospective buyers asking to purchase specifically from private sellers, where no background checks are required.
“At this point, this is the biggest loophole in the background check system,” said Lanae Erickson Hatalsky, director of social policy and politics at Third Way, an organization that has been active in the gun-control movement for years.
