“There is nothing wrong with the populace pointing out the failings of law enforcement.”
No, there isn’t, but because mistakes were made does not mean that the cops have malicious intent. As for burning the house, if it is established that the police started that fire, then too bad. Dorner was not going to give up until he had killed more cops.
Cops are government, they are union people, they are corrupt politically, and the work tends to attract insecure individuals who want to be “cops”, the incompetence, corruption, and lack of mission completing strategies and a typical job security, protect the jobs and bureaucracy and the democrat political machine mentality, explains why nothing changes and internal progress and self corrections are practically unheard of.
This was just another widespread debacle that gave the public a glimpse into what most of us know, law enforcement is just another city job.
