Yes, Virginia, he really is left-handed.
There was a great quote about how photographic evidence would calm everyone down, which the Daily Show or Colbert or whoever said, yeah, right, black man with a gun, _that_ will definitely calm everyone down.
Weird seeing someone shoot a long gun left handed. Not sure I ever have before.
The skeet shooting association's how-to page says that lefties do as well as righties.
"Left handed shooters do just as well as right."
I have never participated, altho it does seem like it would be fun.
