“A man involved in a domestic dispute shot dead six family members and critically wounded a seventh in a suburb of Houston Wednesday, before surrendering to police following a tense standoff,” NBC reports. “Law-enforcement officials said the suspect — identified as 33-year-old Ron Lee Haskell — had a domestic argument involving a divorce before he drove to the home in Spring, Texas, and shot seven family members, including five children.” The scene of Haskell’s mayhem: the home of one of his siblings. After one of those shot told police where Haskell might go next, the cops cornered the killer before he could get to another family member’s home. Gird yourself for the usual blame hurled at guns, gun owners, the NRA . . . all the usual suspects in the eyes of civilian disarmament advocates.
