This 'gun news' is kind of old, it came out early (leaked) last week.
But the point is she didn't buy it, it was gift from her brother when she first moved to Dallas. And as I recall, her brother said she fired it once at a range, hit NOTHING, then put it away where it has stayed.
As to her even owning a gun, that's a 'so what' IMO. Gun grabbing Senator Di-Fi packs heat, as do most of the gun grabbing pols and limousine liberals (Sean Penn).
I agree with you, just because she owned a 45 doesn't mean a hill of beans. I what to know her true feelings about the right to bear arms! How would she have ruled in the Emerson case? How would she rule in cases dealing with 50 Cal's or semi-auto rifles with 30 rd magazines/collapsible stock? Big deal like you most excellently point out Di-Fi owns a gun. Americans need to know where she stands on the 2nd Amendment!
