Misty said the beds were four inches apart. This is an inconsistency. This is not a lie in that she did not mean they were really four inches apart...she meant to say they were four feet apart. It just didn't come out that way.
So I do disagree that all inconsistencies are lies. Sometimes they are simply words or thoughts which get confused under stressful situations.
Inconsistencies do not add up to lies, says police chief
Police officers had different memories of the events leading to Thomas "TJ" Hickey's death but the inconsistencies did not necessarily make them liars, said the Police Commissioner, Ken Moroney.

Inconsistencies in the statements given by Senior Constable Michael Hollingsworth and his partner, Constable Maree Reynolds, "do not necessarily amount to lies".
"The coroner comments about incorrect evidence by several witnesses. It would not be inconceivable there would be inconsistencies in their [the police's] recollections," he said.
