Its a recent tactic of the anti-gun left to make claims (some wild) of owning guns to try to give themselves some sort of gun-owner cred.
Even in our local paper, a certain rabid anti-gun columnist claimed that he likes to hunt with his grandfather's 'Colt double barrel shotgun'- I had to look that one up, and nope, I highly doubt that he's ever fired one, let alone hunts with it.
