Having one's cake and eating it too happens everyday. Remember when the abuse at Abu Ghraib was uncovered? Highest ranking person that spent time in jail for that was a staff sergeant. The officers in charge of the prison claimed that those soldiers who abused prisoners were just a few "bad apples". Well, you can't have your cake and eat it too. Either the commanders were giving orders to abuse or they were unaware of the soldiers under their command violating codes of conduct, tantamount to negligence. You can't have it both ways, logically, but those officers sure did.
