Is there any Hope in Our Police Force?

Is there no more creditabilty left in the PDRM? We have now reached a stage where every comment  made about the PDRM is not only negative but filled with vitriol. One needs only to go through the comments made in Malaysian Insider or Malaysian Chronicles and other online media to experience the fear and anxiety when one is called up by the police. Advice like "be careful", declare your self healthy and not suicidal, etc have been given to those who are being called up for interrogation or who would want to make police reports, especially if the reports are against their own kind. Unless the allegation is captured on CCTV,  like the assault of the 23 year-old youth in Sabah by the director of prisons, there is little hope that the police will act on the report.
The PDRM must blame themselves for allowing the situation to come to such a state. Even though there is concrete proof with self confession, the police are still not taking action. Typical is the case of the sex video by the Datuk T. It is a clear violation of the law, and yet the Trio are still free men. Then we have the police and the AG playing footbal, passing the reports to and fro, under the excuse that they want the cases to be air-tight. But in the end, we all know what will happen. How many high profile cases have been successfully conluded and the culprits punished?
Selective enforcement of the law is another area which the police seem to forget. Water cannon and arrests are common for demonstrators from the Opposition parties, but only warnings and worst, a tap on the wrists for the umno demonstrators. 
So you tell me, IGP, Deputy IGB and Home Minister, how do you expect us to respect the PDRM, with all these selective persecution, prosecution and enforcement being practised openly and blatantly? 
I was born in 1940 and I have lived through all the six Prime Ministers and have seen and experienced the vast changes, and it grieves me to have to spend the twilight years of my life to see my beloved country being destroyed by power crazy people and religious extremists.
