Of course it is in the same condition as it was found. Tragic situation for the family but why would you expect the gun to be sparkly clean when you pick it up from evidence?
Don't think he said they should have cleaned it BUT common sense would say wipe the brain matter off a weapon before returning it to a family member, kind of a "no-brainer" in the common sense department I would think. Takes maybe two minutes to do in a sink I would guess......
