'Knowingly Lied'

'Knowingly lied' is a pleonastic expression. One cannot lie without intending to deceive. And one cannot intend to do X without knowing that one intends to do X. So one cannot lie without lying knowingly: there is no such thing as an unknowing or unwitting lie. It follows that 'knowingly lied' is a pleonastic or redundant expression.  Good writers avoid pleonasm.

Good writers also know when to break rules in the service of what they want to say.
