"We are in a violent society," Stein said on ABC's "This Week." "We're all being caught in the crossfire."
Stephanopoulos said Stein was "saying things that no other candidates are willing to say," and asked how her plan would work "in a society where there are millions of guns."
"Exactly, which is why I used the term something to explore for the future," Stein said. "The context there really was talking about violence and police violence in particular ... It's important to see that it's not just police violence."
The U.S. had as many as 310 million guns in 2009, according to a report by the Congressional Research Service.
In some other countries including England and New Zealand, officers on patrol don't typically carry firearms.
In July, police reform advocates spoke to ABC News about the potential ways to reduce police shootings, including stronger anti-bias and de-escalation training, independent oversight, and a revised description of policing duties.
They did not mention any notion of disarming the police.
