Hero worship is not the answer and may actually contribute to the problem. The solution is basic accountability ie police do not investigate themselves and a change of culture from "war on crime" to community policing. As someone else commented here, the police training actually turns well meaning future officers against the average citizen. An example re: accountability is the California city that significantly reduced complaints by requiring officers to wear cameras. Small sample size but encouraging.
