‘I've never killed anyone…by hand’ – and other types of plausible deniability

MPs have discovered it is an effective ploy to deny doing something, despite indirectly benefiting from hit.

They never made a disabled person to commit suicide; they just took away their financial aid. And they have never personally used a tax haven, even if all their accountants have.
