On a day like today it's easy to run out of racetrack while covering something as basic as traffic. But a flash freeze and an absence of salt trucks sent a lot of people slip sliding away. I mentioned I had a story about guns and you would find it here so ....

This story comes from a column written by David Frum which you can find here. He tells of a group of friends in a car in Georgia who pulled into the wrong driveway. Rodrigo Diaz, aged 22 was at the wheel. The owner of the house, a 69 year old Viet Nam vet came out armed with a rifle which he fired into the air. Rodrigo threw the car in reverse and rolled down the window to apologize for having the wrong house. The man shot him in the head. Police say the old man thought the people in the car were going to rob his house. When asked how he could draw that impression when the car was backing out of the drive an officer said "He's old. He may have been confused".

As Frum offers; perhaps too old to own a gun. Now of course the law and order and pro-gun crowd will make all kinds of arguments about there being a real possibility that Rodrigo isn't a saint and maybe he WAS there to rob the house but in what world do you shoot people in the street who you think MIGHT be on their way to rob your house?

I'm not a hard core gun control guy because I believe in responsible gun ownership but as long as people keep shooting each other for no reason it's pretty clear we need to have a franker discussion of what constitutes responsible gun ownership. With this old guy shooting a young man dead, Gabby Giffords speaking on the Hill and a little girl who played drum corps at Obama's inauguration being gunned down in a Chicago park, the NRA had better start refining its talking points.
