Vice President Biden said Friday that there was “no silver bullet” to deal with gun violence, explaining that the Obama administration was considering a wide-ranging set of policies in the wake of last month’s school massacre in Connecticut.

Biden’s unusual choice for metaphor came after a White House meeting with video game industry executives, who have come under scrutiny for violent ­gun-related themes in their products.

The comments marked the last in a series of meetings held this week by Biden’s anti-gun-violence task force, which he said is “shooting for Tuesday” to forward a set of policy recommendations to President Obama.
