"We know that there is no silver bullet" to deal with gun violence, Vice President Biden told reporters — using a somewhat unfortunate cliche — before a meeting with executives from the video game industry.

The meeting is one in a series of summits being held this week by Biden's task force on how to address gun violence in the wake of Newton, Conn., school massacre. 

"I come to this meeting with no judgement," Biden said. "You all know the judgement other people have made." He declined to elaborate on what that judgment was. 

Asked whether the culture had been coarsened by violent video games, Biden responded, "I do not know the answer to that question."

He said Thursday's meeting with the National Rifle Association and other gun rights groups was "very straightforward, productive," and did not respond to the NRA's complaints about the tenor of the discussion. 

After that meeting, Biden said there was an emerging consensus around “universal background checks” for all gun buyers and a ban on high-capacity ammunition magazines.
