It's only mantling if what was mantled is out in the open. Ah--but where does one draw the line as to when "by implication" equals "out in the open"? I once wrote a petition stating that the three-year-old child consistently wandered all over her neighborhood by herself, including crossing streets. Now to me, the child's age rendered it automatic that this put the child at risk. But the prosecutor wouldn't sign it until I'd added a sentence to that effect.
