the sun haven't themselves seen the bank statements, just emails talking about the statements. it's very careful wording - no bank statements have been shown to BBC either, they have just described them to the BBC
the sun have not seen any screenshots either nor have the BBC have been shown them - they have just been told the family has them...again, very careful wording
as you say, the sun believe they're in the clear here (and pains me to say they probably are), because everything they say, they just point to what the parents have said.
