Every time NBC sportscaster Bob Costas trots out his ill-informed, ill-considered opinions on gun control, his bias against [mostly] African American athletes comes into sharper focus. The latest installment of “Whose Gun Rights Are They Anyway?” has Bob flapping his anti-gun gums at Piers Morgan, the ex-pat CNN talkmeister whose understanding of the Second Amendment is about as comprehensive as Shimrit As‘ understanding of barodynamics. This time ’round, Costas has modified his “guns suck” remarks to “it’s infinitely more likely that something bad will happen if you’re armed than something good will happen.” I guess those 1m-plus defensive gun uses per year in the U.S. don’t figure. At least not in Bob’s world.
