"If Jovan Belcher didn't possess a gun, he and Kasandra Perkins would both be alive today," Mr. Costas suggested, correctly in our view. Domestic disturbances can turn deadly even without a gun — witness the case of a Baltimore woman suspected in the killing this weekend of her 2-year-old son who died of a severe laceration — but firearms assuredly raise the level of danger. Mr. Costas quoted Kansas City-based writer Jason Whitlock on the link between gun-related deaths and easy access to firearms: "Our current gun culture," Mr. Whitlock wrote, "ensures that more and more domestic disputes will end in the ultimate tragedy. ... Handguns do not enhance our safety. They exacerbate our flaws, tempt us to escalate arguments, and bait us into embracing confrontation rather than avoiding it."
