Original Post: The anti-cop cop-killing cop told us this was coming. California police spent Thursday morning on a statewide manhunt for Christopher Jordan Dorner, an ex-LAPD officer who they suspect is connected to the shootings of three police officers today and two killings over the weekend. The search for Dorner resulted in two innocent bystanders — newspaper deliverywomen — being shot, but the most frightening part of the mayhem that's currently shutting down the California just system came before any bullets flew: Dorner warned of the attacks in a lengthy, winding screed accusing dirty cops of maintaining Rodney King-era tactics — and warning of more attacks to come.

According to The Los Angeles Times, Dorner "wrote an online manifesto on his Facebook page, threatening to harm police officials and their families, law enforcement sources said." That unedited screed, which was published on Monday, is about 11,000 words long — part suicide-style note, part political rant, maybe even part target list — and has finally surfaced online. It may be the ravings of a fired officer gone on a rampage, but it also raises questions about what's wrong with the LAPD — or at least what the police could have done to prevent the killings, and where Dorner might be headed next as the search now extends from Las Vegas to LAPD headquarters, where snipers are currently on the roof in case Dorner returns.

In the letter, Dorner nearly admits to the shootings to come:

I know most of you who personally know me are in disbelief to hear from media reports that I am suspected of committing such horrendous murders and have taken drastic and shocking actions in the last couple of days. You are saying to yourself that this is completely out of character of the man you knew who always wore a smile wherever he was seen. I know I will be villified by the LAPD and the media. Unfortunately, this is a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name.

And his reasoning — albeit rambling — is that he believes the LAPD is a fudamentally corrupt organization:

The department has not changed since the Rampart and Rodney King days. It has gotten worse. The consent decree should never have been lifted. The only thing that has evolved from the consent decree is those officers involved in the Rampart scandal and Rodney King incidents have since promoted to supervisor, commanders, and command staff, and executive positions.

Those are serious charges and pretty intense if true, though the narrative of police departments being corrupt isn't exactly foreign — and certainly not in Los Angeles. But what cemented Dornan's belief is the incident that got him fired:

In 8/07 I reported an officer (Ofcr. Teresa Evans/now a Sergeant), for kicking a suspect (excessive force) during a Use of Force while I was assigned as a patrol officer at LAPD’s Harbor Division. While cuffing the suspect, (Christopher Gettler), Evans kicked the suspect twice in the chest and once in the face. The kick to the face left a visible injury on the left cheek below the eye. Unfortunately after reporting it to supervisors and investigated by PSB (internal affairs investigator Det. Villanueva/Gallegos), nothing was done.

Dorner, as ABC News reports, was fired for making false statements in that case. But it's not like Dorner wasn't supported. According to the AP, the father of the man who Dorner claims his fellow officer kicked offered testimony that lined up with Dorner's claim. But that didn't change the outcome, and Dorner's firing seems to be the basis for the rampage:

I have exhausted all available means at obtaining my name back. I have attempted all legal court efforts within appeals at the Superior Courts and California Appellate courts. This is my last resort. The LAPD has suppressed the truth and it has now lead to deadly consequences.

And Dorner goes on to name specific officers:

Bratton, Beck, Hayes, Tingirides, Eisenberg, Martella, Quan, Evans, Hernandez, Villanueva/Gallegos, and Anderson. Your lack of ethics and conspiring to wrong a just individual are over.Suppressing the truth will leave to deadly consequences for you and your family.

The chilling part of the story behind his screed is that police believe Dorner has already made good on his threat of taking out these officers' families: Monica Quan, thedaughter of officer Randy Quan (mentioned above), and her fiancé were found shot to death over the weekend, but at the time police had not tied Dorner to those murders. "Police say they are taking extra measures to ensure the safety of officers and their families," ABC News reports.
