I have seen lots of blue steel wallets..../s
The policeman's lawyer said he had a gun, and during a news briefing officials confirmed that a handgun had been recovered from Castiles body. But they do not say where, or at least I haven't heard, where on the body it was recovered from. That may indeed be a gun on his lap, however, supposedly he was retrieving his wallet as well. A majority of the object in his lap is covered by a piece of paper, and the picture is of poor quality and blurry.
All I can say is that you both must have extremely excellent eye sight to state positively that it is a gun, and not a wallet. I myself cannot state what it is, and to me it could be either either item, gun or wallet, or even another item.
