Mr Stein has got it.
He is stopping Mike Young from blaming others for why he didn't raise his concerns. And he should take some personal responsibility.
Mike Young is not loving this.
He seems to think that because Lesley Sewell, Paula Vennells, Fujitsu didn't say anything, then it isn't his fault.
But he can't gave it both ways. He can't say on one hand that he identified the scandal long before anyone else, but because no-one else spotted it, he isn't to blame for not raising it.
It's a nonsensical argument.
