Some lawmakers are hoping the insurance market might offer the best incentives to lessen firearms-related violence.

A bill filed Friday in Massachusetts would require gun owners to purchase liability insurance in the event their gun is used to injure.

Supporters say insurance policies would give those injured by a weapon a legal recourse while also creating market-based incentives that could reduce accidents and fatalities.

Gun owners could see their insurance costs drop, say, if they agreed to take firearms training course and properly stored their weapons. (Associated Press)
