Caught Red Handed

I have just marked all the police papers, but one of the officers tells me, "The papers have all been tampered with, Ma'am. All the guilty P.O.'s have signed their names on those documents."
I have to dispose of the evidence or the good name of our unit will be at stake. I throw the papers down the toilet but find the flush handle has been removed! I realise too late that this is a trap to test corrupt P.O.'s and I have been caught red handed.
