It depends on what a cop does when he sees misconduct by others. Christopher Dorner reported misconduct, but was ostracized afterward. He sought justice in his own way afterward:
Not really relevant, but the ridiculous (and secret) police response once they knew they were being targeted had bad consequences for others too. I have a house near where this multi-agency incident (links below) occurred and there was so much gunfire for such a long period that I knew it had to be cops doing the shooting.
Dorner murdered two people who had nothing to do with the LAPD. One was a campus security guard at the University of South Carolina and the other wasn't any sort of cop at all, she was a basketball coach. Even if you believe all of Dorner's allegations against the LAPD, Dorner was still a mass murdering psychopath who targeted and murdering innocent people. In light of that, why would you believe any of his allegations in the first place? Hero worship of Dorner is an insane 4chanism, shame on you. Dorner was nothing more than another murderous cop.
I'm pretty sure that I did not express any sympathy or support for what Dorner did in my post. I do believe though that it's more likely than not that the excessive force he reported actually occurred. His record up to that point was exemplary. After he snapped, his murderous rage was not typical behavior for law enforcement, but it is a fact that psychopathy is far more prevalent in police officers than in the general population. One could argue about whether this is because psychos are drawn to the police profession, or that the nature of the work the police do causes mental problems.
There was no justice in it. You're also taking for granted that the misjustice he claimed to have seen actually happened. Taking seriously the word of a man we know murdered innocent people.
I'm not taking anyone's word for anything. I'm just speculating at what triggered him and why. He obviously believed that he was wronged when the report he filed was dismissed, and he was subsequently fired. If he filed a false report, then he deserved to get fired. If he filed an accurate report, and the (documented) culture of corruption among LAPD conspired to discredit him (and destroy his life), he may have felt that his actions were justified.
Again, you need to stop confusing my analysis for support and sympathy for Dorner. He obviously exhibited some mental problems and very poor judgement, but stressful conditions can do that to otherwise good people:
